Question

If the equilibrium constant,  ,for a reaction increases upon heating,the reaction must have been endothermic.

Quizplus · Accepted Answer

An increase in the equilibrium constant (K) as temperature is increased indicates that the reaction is endothermic. This is because an endothermic reaction absorbs heat, which is a reactant in the equilibrium expression. As temperature is increased, more heat is available to drive the forward reaction, resulting in an increase in K.
