What effect does increasing temperature have on the equilibrium position of exothermic reactions?

In exothermic reactions, heat is released as a product of the reaction. According to Le Chatelier's principle, if you change the conditions of a system at equilibrium, the system will shift in a direction that counteracts that change. When the temperature is increased, it can be thought of as adding heat to the system.

For exothermic reactions, increasing the temperature shifts the equilibrium position to favor the reactants, as the system attempts to absorb the added heat by favoring the reverse reaction, which consumes heat. This results in a decrease in the concentration of products and an increase in the concentration of reactants, therefore causing a shift to the left.

This principle is crucial in understanding how temperature changes affect chemical reactions and their equilibria, informing decisions in industrial processes and laboratory settings where temperature control can enhance yield or reaction efficiency.
