I was asked this question at class,
What is the thermal state of a reaction at equilibrium, the forward reaction of which, is exothermic?
I conjectured that since the forward (exothermic) reaction and the backward (endothermic) reaction occur at equal rates, the reaction at equilibrium would be athermic since there doesn't seem to be any net heat evolution. However, my teacher said this was not true.
Could someone tell me where I'm going wrong with my reasoning?
