When Q=K

[OishiBhattacharya2K]

Just for clarification, when Q=K, is it safe to assume that the reaction is at equilibrium?

[Chloe Fuson]

Yes, if you start out solving for Q because you are unsure whether a reaction is at equilibrium, and then find that the value you calculate is equal to K, then you now know the reaction is at equilibrium.

[alexjung1A]

Yes, this is always the case.

[Emily Nguyen 3L]

Yes, if the Q (reaction quotient) value that calculates the ratio of product to reactant concentration is equal to the K (equilibrium constant) value, then the reaction is at equilibrium.

[Terrence Chi]

Hi, if Q=K, then the system is at equilibrium since the concentration of product over reactant is equal to the equilibrium constant K. Hope this helps!

[505706331]

yes. whenever q=k that means that the reaction is at equilibrium.

[Sidney Shah 3H]

Yes, since Q is the ratio of products to reactants, if that ratio is equal to K, then you can assume rxn is at equilibrium

[Jane Wang 1E]

If it is at the same/constant temperature, then yes.

[405669838]

Yes, if Q=K then the reaction is at equilibrium.

[Jacqueline Vargas 3L]

Yes. This question is relevant when we are studying a reaction. We can compare a given K value to the a Q value based on the information we have of the reaction (concentration of products and reactants) in order to determine if the reaction has reached equilibrium or if it has not, which side of the reaction will it favor.

[Kathryn Heinemeier 3H]

Yes it is safe to assume that the reaction is at equilibrium.

[Alekhya_Pantula_2E]

Yes essentially Q is used as a measure to see if the reaction has reached equilibrium, so once Q=K then we can confirm that the reaction is at equilibrium.

[205282258]

Yes, if Q = K then the equation is at equilibrium.

[Dillon Taing 3H]

Q is the product to reactant ratio at any given time in a reaction while K is the product to reactant ratio at equilibrium. When Q=K, then neither side of the system is favored and the reaction is in equilibrium.

[Sasha Gladkikh 2A]

Hi,

When Q = K, the reaction is at equilibrium—and will remain so until the system is disturbed (e.g. if heat is added or the pressure is increased).

Here is a diagram that illustrates the comparison between the reaction quotient (Q) and equilibrium constant (K):

[Alena Zhu 2I]

Yep! The reaction quotient is usually measured and calculated multiple times as a reaction precedes, and when it finally equals K, it indicates that the system is at equilibrium and the reactions are occurring at the same rate.

[Aaron Martinez]

Yes, if Q=K, then the reaction is at equilibrium. This will always be the case. If Q does not equal K, then it's not at equilibrium.

[Madison Kiggins 1E]

Yes, if Q is equal to K that means that the reaction is at equilibrium. If Q is any other value besides K it is not at equilibrium.

[Joseph Lee]

Yep! When the reaction quotient is the same thing as the equilibrium constant, then the reaction is at equilibrium.

[Mia Orr 3B]

Yes, when Q is equal to K it means that the reaction is at equilibrium. When Q is any other value, it means that the reaction is not at equilibrium. Hope this helps!

[Caitlyn Lo 2F]

Yes, when Q=K this means that the reaction is at equilibrium.

[Samir Panwar]

Yes, if the ratio of products to reactants equals K then we can say Q=K, which means the reaction is at equilibrium.

[Tanvi Akula 2K]

When Q and K are equal, that means the reaction is at equilibirum.

[Amy Huynh 1B]

Yes, when Q=K, the reaction is at equilibrium.

[805401611]

Yes, this is the case as K is the numerical value of Q at the "end" of the reaction when equilibrium has been reached. Hope that helps!

[Ramya_Paravastu_1H]

Yes! K is the ratio of the concentrations of the products and reactants at equilibrium. When the reaction quotient (the same ratio, but at any given point in time or progression of the reaction) is equal to K, the system is at equilibrium.

[Mya_Chiarappa_2C]

Yes, Q is basically the same as K in how it is calculated, it is just called K at equilibrium and Q when not at equilibrium. When K = Q it is at equilibrium.

[905565862]

Yes, Q=K means it is at equilibrium.

[Collin Le 3I]

Yes, Q and K are calculated the same way, so if Q is equal to K, the system is at equilibrium.

[Nicole Friday 1E]

Yes, for all cases when Q=K the system is at equilibrium.

[Rebekah Jung 1C]

Yes, when Q=K the reaction is at equilibrium. If Q<K then we can predict the reaction will favor the products until K is reached. When the calculated Q value > K then we can predict the reactants will be favored, going right to left.

[William Huang 1K]

Yes, Q will proceed to move in the direction that gets the system to equilibrium (when Q=K).

[Amanda Pineda 3H]

If Q=K then yes this means that the reaction is at equilibrium. The reaction quotient, Q, will equal the equilibrium constant,K, meaning the reaction itself is at a balance.

[405479701]

yes, when Q=K it is at equilibrium.

[Emilie Otterson 1C]

Yes, if Q=K then the reaction must be at equilibrium. Since K is the equilibrium constant (signifying the reaction is at equilibrium), if the reaction quotient, Q, is equal to it, then the reaction has reached equilibrium.

[Achyutha Kodavatikanti_3H]

Yes, when Q = K the reaction is considered to be at equilibrium. Q measures the relative product and reactant concentrations at a specific point in time, which may or may not be equal to the product and reactant concentrations at equilibrium (K).

[Myra Goraya Dis 2E]

Both Q and K are derived through the concentrations of products/reactants. If Q and K are equivalent that means the system is at equilibrium and the value is no longer "Q" but instead it is "K"

[Clarence Clavite 2K]

Yes, when Q=K, at that point in time, the reaction is at equilibrium.

[Vanessa Bartoli 1C]

Yes, when Q is = to K, it indicates that the reaction is at equilibrium. Conversely, we know that when q is not = K, the reaction is not at equilibrium.

[Neha Mukund]

Yes, when Q=K the reaction is at equilibrium.

[Caitlin_Doak_2H]

If the Q is a big number because the numerator is large, that means there are more products so it would need to shift left towards reactants. If it is a smaller number, then Q would be more reactant heavy and shift to the right toward the products.

[kayleec1004]

When Q = K, the reaction is at equilibrium until the system is disturbed.

[Jillian Sarquiz- 2B]

Yes, when Q=K, the system is at equilibrium.

[Acharya Ranawat 3E]

Yes. You can assume that it is at equilibrium since the ratios of the concentrations are the same. Hope this helps!

[JennyZhu1K]

Yup! It is safe to assume the reaction is at equilibrium

[205705413]

Yes when Q=K, it is at an equilibrium.

[Esmeralda_Solis_2D]

Yes its basically means that when Q=K the system is already at equilibrium.

[RCortez_1A]

Yes, when Q = K it is safe to assume that the reaction is at equilibrium since K is used only when the reaction is at equilibrium.

[Michael 1G]

Yes. Since k is the constant for the reaction at equilibrium, if Q is equal to K it must mean that equilibrium has been reached.

[Jessica Servoss 1H]

When you are checking if a reaction has reached equilibrium and you compare Q to K (which would be given), and Q=K, the reaction is at equilibrium.

[Jessica Sun 2I]

Only when the reaction quotient(Q) equals the equilibrium constant(K) will the reaction be in equilibrium.

[Sabira Mohammed 3I]

Yes, when Q is equal to K that means the reaction is at equilibrium

[Anna Furton]

Yes, when Q=K, the reaction is at equilibrium. This is because K is the ratio of product concentration over reactant concentration at equilibrium, and Q is the exact same thing but when the reaction is at an undetermined state. Therefore, when they are equal, the reaction state is determined to be equilibrium.

[Alice Weber 3I]

Yep. K is the equilibrium constant so if Q is the same as K, you assume the reaction is in equilibrium.

[indigoaustin 3H]

Yes, when Q=K the system is at equilibrium. The formulas for Q and K are the same, K just specifies the concentrations/pressures are at equilibrium.

[erud]

Yes, I'm pretty sure at least in this point of the class we can assume that.

[Jaipal Virdi 2I]

Yup! if q=k, it is at equilibrium since they use the same formula, the only difference is the context in which you label them.

[Daniela G 2C]

Although a very rare instance, when Q=K, it is safe to assume that the reaction is at equilibrium.

[Samantha Toscano 2C]

Yes if Q and K are equal to each other then they are at equilibrium.

[Baffour Adusei 1L]

Hi! Yes, when Q=K, it is safe to assume that the reaction is at equilibrium.

[Skylar Lo 2C]

Yes, the reaction is at equilibrium when Q=K.

[Kayla Ziebell 1H]

Yes if you have K, and solve the ratio of products over reactants and find that Q is equal to K, then you can assume that the reaction is at equilibrium.

[Ashrita Singh 2F]

Yes, when Q=K, the reaction is at equilibrium.

[Holly Do 2J]

Yes the reaction is at equilibrium when Q=K. This is because K is the equilibrium constant while Q is the ratio when the reaction is NOT at equilibrium therefore if Q DOES equal K, the ratio is equal to the equilibrium ratio making it at equilibrium.

[trevina_brown_2A]

Yes when Q=K the reaction is at equilibrium

[elliemehrara]

Yes, when Q = K, it means that the reaction is at equilibrium.

[Eszter Kovacs 1A]

Yes, if Q=K the reaction will be at equilibrium.

[Hannah Thornton 1F]

Yes, when Q=K, this means that the reaction is at equilibrum.

[Amy Jordan 2A]

Hi, yes when Q=K the reaction is at equilibrium. You can compare the two to see which side is favored as well. Hope this helps!

[Madison Rhynhart 3H]

Yes ! this is true because if Q is the ratio of products to reactants and K is the ratio of those at equilibrium and then Q =K then we can assume the reaction is at equilibrium.

[Talia Tam 3L]

Yes, when Q=K it means the reaction is at equilibrium.

[Nicole Friday 1E]

Yes, when Q=K this means that the reaction is at equilibrium.

[Madeline Ellmore 2C]

When Q = K, the reaction is always at equilibrium! Hope that helps!

[305670352]

Yes, when Q=K, the reaction is at equilibrium.
