If we have an endothermic rxn, and we increase the Temp;

I know that this will favor the products and drive the rxn to the product side. I also know that Keq only changes with changes in Temp. My questions is, can we assume that the Keq will increase? Or is the shift to the product side not related to how Keq changes? Thanks in advance.

You're essentially adding heat if you raise the temperature. Think of heat as just another product (exothermic) or reactant (endothermic) and use le chatlier's principle to determine the direction of change.

I would think that if heat is a reactant (endothermic) then the reaction will shift to the right resulting in an increase of product relative to reactants and as a result an increase in Keq. If it's exothermic the reverse is true.
