Endothermic reactions are the opposite. The new bonds require more energy. This comes from heating the substances, or sometimes, comes from the surrounding environment. Absorbing heat energy from the environment makes everything decrease in temperature so the reaction 'feels' cooler.
heat will be absorbed and the products will be formed faster exothermic reaction will undergo spontaneously as it does not require any energy while endothermic reaction has to be supplied with energy to happen therefore exothermic reaction will be faster than endothermic reaction
