Question

Why did the temperature change or not change during the reaction?

Answer 1

When substances react and the temperature of the mixture decreases, the reaction is endothermic. ... If a reaction is exothermic, more energy is released when the bonds of the products are formed than it takes to break the bonds of the reactants. This is the reason for temperature change during a reaction.
