affect of temperature on K
if a reaction is endothermic, and the temperature is raised, the rate constant of the forward reaction also is raised. Likewise, if a reaction is exothermic, does that mean with an increase in temperature k' will increase more than k of the forward reaction?

Re: affect of temperature on K
I believe for endothermic reactions, like you said if the temperature is raised forward rxn is favored.
In contrast, I believe for exothermic rxn, if T is raised backward rxn is favored

Re: affect of temperature on K
If the reverse reaction is favored and k' is the constant for the reverse reaction, shouldn't that one increase as well? I mean, I know it's a constant, but since the temperature has an effect on k then it should change right?
Re: affect of temperature on K
@ Daniel Chen 2L , I am also curious about that...
Something else that confused me was when the textbook would say the temperature that did not seem like a standard temp, but then would say what k equals. I'm pretty sure that I should just use the k and note that the temp was only given for context.
I'm not missing some calculation for change in temp for the standard k at room temp, right?

Re: affect of temperature on K
If the forward reaction is exothermic, then with an increase in temperature the reverse reaction is favored, meaning that k'>k
