Increasing temperature tends to favor endothermic reactions, as these reactions absorb heat, enhancing their likelihood of occurring.

To elaborate, an endothermic reaction is characterized by the absorption of heat from its surroundings, which is often perceived as a cooling effect. The term “endothermic” is derived from the Greek words “endo,” meaning “inside,” and “therm,” meaning “heat.” Thus, in an endothermic reaction, heat is drawn into the system from the environment.

The rate of a chemical reaction is influenced by several factors, with temperature being a significant one. According to collision theory, for a reaction to take place, reacting particles must collide with sufficient energy, referred to as the activation energy. When temperature increases, the kinetic energy of the particles rises, causing them to move more rapidly. This increased motion results in more frequent and energetic collisions, which enhances the likelihood that the particles will surpass the activation energy barrier, thereby accelerating the reaction.

In the context of endothermic reactions, the heat supplied by the temperature increase is absorbed by the reaction itself. This absorption effectively lowers the activation energy required for the reaction to proceed. Consequently, the reaction rate increases, making it more probable for the reaction to occur.

It is crucial to recognize that while raising the temperature typically benefits endothermic reactions, it does not guarantee that the reaction will take place. Other factors, such as the concentration of reactants and the presence of catalysts, also play a vital role in determining the reaction rate. Nevertheless, if your goal is to promote an endothermic reaction, increasing the temperature is generally a promising strategy.
