Heat Capacity vs favoring side

[Marriyum Aftab 2E]

Does heat capacity have anything to do with which side of the reaction gets favored? Like when heat is added to the system, it increases the enthalpy, but does it affect which side of the reaction is favored?

Hi,

we know that according to Le Chatelier's Principle, when we apply heat/or increase temperature to a system, the followings can occur:

In a forward rxn that's exothermic, or delta H (change in enthalpy)= negative, increasing the temperature would increase the production of reactants and decrease the production of products. In other words, the reverse reaction is favored.

In a forward rxn that's endothermic, or delta H = positive, increasing the temperature would increase the production of products, where the forward reaction is favored.

Adding heat will favor the endothermic fwrd reaction more than the exothermic frwd reaction according to Le Chatelier's Principle that we learned during our equilibrium unit.
