What happens to the relative amount of products at equilibrium in an endothermic reaction when the temperature is decreased?

In an endothermic reaction, heat is absorbed from the surroundings. According to Le Chatelier's principle, if a change is made to a system at equilibrium, the system will adjust itself to counteract that change. When the temperature in an endothermic reaction is decreased, it is akin to removing heat from the system.

Since heat is a reactant in an endothermic process, reducing the temperature effectively shifts the equilibrium position toward the left, favoring the formation of reactants. This shift results in a lower relative amount of products present at equilibrium, as the system works to counteract the decrease in temperature by producing more reactants. Thus, the correct conclusion is that the relative amount of products decreases when the temperature is lowered in an endothermic reaction.
