For an exothermic reaction at equilibrium, what does raising the temperature do?

A.Shifts the reaction toward reactants and decreases K

B.Shifts toward products and increases K

C.Has no effect

D.Doubles the rate of the forward reaction only

Explanation

Core Concept

Adding heat stresses the system; it shifts to consume heat, favoring the reverse (endothermic) direction. For exothermic reactions, K shrinks as T rises.
