What is the relationship between temperature and the equilibrium constant k? Is it a direct or indirect relationship? And why?

Answer 1

A + B + heat = C
Keq = (C)/(A)(B)
For endothermic reactions increased T will mean the rxn shifts to the right which makes C larger, A and B smaller so K is larger. For exothermic rxns
A + B = C + heat
K = (C)/(A)(B)
For increase in T rxn shifts to left, C becomes smaller, A and B larger so K decreases.
