How does changing the amount of reactants affect the change in temperature of a chemical reaction?

Changing the amount of reactants in a chemical reaction can significantly influence the temperature change observed. If more reactants are added, the reaction may produce more energy, leading to a greater temperature increase, assuming the reaction is exothermic. Conversely, if the amount of reactants is reduced, the reaction may generate less energy, resulting in a smaller temperature change. Additionally, the reaction rate may also be affected, which can further influence the temperature change over time.
