change in K

Postby Shreya Patel- 2D » Sun Jan 10, 2021 7:22 pm

I know that K does not change when there is a change in pressure, but does that mean temperature is the only thing that changes K?

Yes, a change in temperature is the only thing that changes K I believe.

I believe so, in lecture he said that it is the only thing that changes k, and our textbook describes k as temperature dependent.

Yes, K is only affected by the change in temperature.

If equilibrium is temperature dependent would it it also be time dependent? (time from initial temp to equilibrium temp)

Correct temperature is the only thing that changes K

K is unaffected by any change except for changes in Temp.

because K is a constant, the only thing that changes K is temperature :)

Yep just temp in K

Temperature is the only factor that affects K. For instance, if you are dealing with an endothermic reaction, and you increase the temperature, the system will try to offset this increase in temperature by shifting towards the products. This will cause the product's concentration to increase and, thus, so will the equilibrium constant since it is the ratio of products over reactants.

Yes, a change in temperature is the only factor that can change K.

My TA told me that there are other factors that affect K, so you may find others if you look it up, but he said that temperature is the only one we need to know now and that we likely will learn other ones later in the chem series

From what we have learned so far I believe temperature is the only thing that changes K.

Just as stated from before, K can only be altered by temperature

Hi,

Yes, temperature is the only change which affects the value of the equilibrium constant K.

Hope this helps! :)

Temperature does change K. The only two variables that can change K are temperature, and the exact reaction that is occurring. Change the reaction or change the temperature, you change K.

Only temperature will change the K value. Any other change in parameters such as pressure/volume will result in a change in concentration.
