Factors Affecting k

[Sarah Zhari 1D]

Can the rate constant (k) of a reaction change? If so, how?

[Vinita Saxena 2I]

Yes, it can change if the temperature changes, that is the only way it can change

[Selena Yu 1H]

Yes, the rate constant can change. It can change due to temperature. The rate constant is related to temperature through the Arrhenius equation.

[Daniel Toscano 1L]

k = A exp( -EA/RT )
this shows how it can be changed

[Cindy Adiwidjaja 1B]

It can only change with temperatures.

[Myka G 1l]

The rate constant k is similar to the equilibrium constant K in that it is only affected by a change in temperature.

[Tanmay Singhal 1H]

temperature is the only way to change k

[Celine 1F]

rate constant can change due to temperature changes

[ShravanPatel2B]

Temperature can have an affect on the value of the equilibrium constant. This problem was also on the midterm i believe.

[Jacob Motawakel]

yes k can change, but only due to temperature.

[Michelle Xie 2B]

it changes with temperature.

[Leila_4G]

Also, k is a intensive property, not an extensive property, right?

[Matthew Tsai 2H]

Generally, k increases with temperature.

[Chris Charton 1B]

I believe we only go over temperature changing rate, however it can be changed by altering activation energy as well(adding or removing a catalyst)

It is related in the Arrhenius equation; k=Ae^(-Ea/RT)

I think we have to understand the concept of catalysts, but not necessarily how to compute an equation with them.

[SMIYAZAKI_1B]

The rate constant of the equation can alter in two ways: Changing temperature and addition of the catalyst. This can be considered as mixing salt into the water. If you add heat into the water, the molecules will vibrate even more which causes it to dissolve even more, and if you add some sort of proteins, it would be helpful to decrease the activation energy which means that because you don't need that much energy per reaction process, you can easily allow the equation to take place.

[905373636]

Yes, it can change if the temperature changes, that is the only way it can change

Isn't the addition of a catalyst also a way to change it?

[Alfred Barrion 2H]

k can only change when there is a temperature change.

[Moura Girgis 1F]

A change in temperature is a factor that would affect k

[Libby Dillon - 1A]

In lecture it was said that k can be affected by both temperature and activation energy. I think if these values remain constant, then k will go unchanged for the problem.

[MinjooPark_3I]

I actually learned this in Chem 20L but k depends on the temperature and catalysts(enzymes). I believe the catalysts lower the activation energy and increase reaction rate.

[Massimo_Capozza_1G]

The only way k can change is by a change in temperature

[DMaya_2G]

k can only change with temperature and the activation energy.

[Mursall M 2A]

The rate constant can only change if temperature changes!

[Sara Sandri 2B]

The only way a rate constant can change is if the temperature is changed.

[Sejal Parsi 3K]

Temperature is the only way to change K.

[VincentLe_3A]

The only factor which affects k is a change in temperature.

[Inderpal Singh 2L]

Temperature will change k, but we have not gone into it with too much detail I believe.

[Brandon Le 3C]

The rate constant k can be altered if the temperature is changed, or the activation energy is lowered by introducing a catalyst into the reaction.

[Annie Liang 3D]

The rate constant (k) can change with temperature or activation energy.

[Darlene Lien 3E]

Temperature affects the rate constant, K!

[Sukhkiran Kaur 3I]

yes it can change due to a change in temperature.

[SamanthaTolentino 3D]

Yeah, k can change but only through a change in temperature.

[LeahSWM 2E]

k is only affected by change in temperature!

[Adrienne Yuh 2B]

It is only affected by temperature.

[Ximeng Guo 2K]

If a catalyst is added, will k change?

[Nina Fukui 2J]

rate changes with temperature change

[Claudia_Danysh_2B]

Yes, temperature can change the rate constant!

[Karina Grover 1A]

Temperature is the only thing that influences k. When you increase temperature, the rate constant increases (as consistent with the Arrhenius Equation) and the reaction proceeds much more quickly.

[Kyle Dizon 3A]

Temperature is the only factor that has the ability to affect K.

[Aarushi Verma 2I]

K is affected by a change in temperature!

[Sheryl Ocampo 1D]

Only a change in temperature!

[Gwirnowski 3B]

Temperature is the only way to change the rate constant K

[Stacey Phan 2I]

The only way K can change is if you change the temperature

[DPatel_2L]

It will only change due to a temperature change

[Sophia Kalanski 1A]

yes! It can only change when the temperature changes

[Jiapeng Han 1C]

The rate constant changes as temperature changes. Increasing the temperature increases rate constant K.

[Adam Bustamante 1I]

temperature is the only thing that can cause k to change.

[Katie Nye 2F]

I think temperature is the only factor that changes k. A catalyst also changes the rate of the reaction but we haven't done a lot with those yet.

[Dane_Beasley_1E]

Only thing that can cause k to change is temperature.

[Justin Zhang_1A]

K can only change depending on the temperature.

[Keshav Patel 14B 2B]

The rate constant K can only change when temperature changes!

[Britney Tran IJ]

the constant k is affected by any changes in temperature!

[Brian Nguyen 2I]

K can indeed change, but only from a change in temperature.

[Karen Zheng_2K]

It can only change through temperature!

[Presley Gao 2C]

Yes, the rate constant (k) of reaction can change by a change in temperature only.

[Carly_Lipschitz_3H]

K, the rate constant, can be changed by temperature change.

[abby hyman]

K, the rate constant, can only be changed by the temperature

[Mary Shih 3J]

temperature is the only factor that can change k

[Taylor Newville 1C]

In today's lecture, Lavelle said that k can change with temperature, activation energy, and the frequency factor. The rate constant determines the speed of the reaction, which increases with increasing temperature, decreases with increasing activation energy, and increases with increasing frequency of collisions. However, the frequency factor A is often considered constant. All of this is shown by the Arrhenius Equation.

[Tobie Jessup 2E]

K can only be changed if there is a temperature change, it is measure experimentally for a specific reaction.

[Isabella Cortes 2H]

i believe that there are two ways to change k: changing temperature and adding a catalyst

[Sreeram Kurada 3H]

Temperature only affects k

[Kaili Valenzuela 2B]

K can only change by a change in temperature

[Lily Anne Garcia 1C]

only temperature affects k

[Morgan Gee 3B]

The rate constant can be affected by temperature.

[Simi Kapila_3E]

Similar to the equilibrium constant K, k can only change with a change in temperature. Remember the temperature dependence of K.

[Sheryl Ocampo 1D]

only temperature!

[Sukhkiran Kaur 3I]

Yes it can be changed by a change in temperature.

[Kyla Roche 2K]

rate constant k changes due to temperature. rate=k(concentration) and when you change the temperature, the rate changes but temperature doesn't impact concentration thus it must be changing the rate constant. Increasing temperature increases rate thus increases rate constant. On the other hand, decreasing temperature decreases rate thus it decreases the rate constant.

[Chudi Onyedika 3A]

It can be changed when there is a temperature change.

[Lung Sheng Liang 3J]

Equilibrium constant k, can only be affected by increasing the temperature.

[Muskaan Abdul-Sattar]

The rate constant, k, can change due to a change in temperature.

[Ethan Laureano 3H]

Just temperature :)

[Taha 2D]

temp

[Joseph_Armani_3K]

Yes, either by changing the temperature, or by changing the activation energy via a catalyst, as per the Arrhenius equation:

[Raashi Chaudhari 3B]

k is affected by temp changes !

[Mina Tadros 3L]

The rate constant, k, just like the equilibrium constant, K, is affected by a temperature change.

[Kaleb Tuliau 3E]

k generally increases with temperature

[Kiara Phillips 3L]

Yes, K only changes if there is a change in temperature.

[Kiana Tashakori 1D]

The rate constant can change if theres a change in temperature!

[reyvalui_3g]

If there is a change in temperature, k changes as well.

[Diana Aguilar 3H]

Hi! Only a change in temperature can change K!

[Gabe_Ek 1G]

I believe the rate constant only affected If there's a change in temperature.

[RyanKopeikin_2I]

The rate constant is affected by temperature and activation energy. Decreasing the activation energy by using a catalyst would increase the rate constant. Increasing temperature would also increase the rate constant.
