What type of reaction causes the equilibrium to shift to the right when heat is applied?

An endothermic reaction is characterized by the absorption of heat. According to Le Chatelier's Principle, when an external change, such as an increase in temperature, is applied to a system at equilibrium, the system responds by shifting the equilibrium position to counteract that change. In the case of an endothermic reaction, adding heat shifts the equilibrium to the right, toward the products, as the system "absorbs" the added heat energy to facilitate the reaction.

This behavior can be illustrated with a simplified endothermic reaction represented as A + heat ⇌ B. When heat is supplied, the equilibrium shifts right, favoring the formation of product B. Understanding this principle is crucial for predicting the behavior of chemical reactions under varying temperature conditions.
