WebFeb 7, 2024 · I.e., just as Δ G is G p r o d − G r e a c t, Δ C p is C p, p r o d − C p, r e a c t. Hence, as the temperature increases, if (say) C p, p r o d > C p, r e a c t, then: ( ∂ Δ H ∂ T) p > 0, which means the reaction will become less exothermic/more endothermic as the temperature increases. Note, however, that C p is itself also temperature-dependent.
