.
Statement 2 : In an exothermic reaction the products have less potential energy than the reactants.

Q. If the reactants are at a higher energy level than products, the reaction is exothermic. The activation energy of a forward reaction is less than that of the backward reaction. That means, the energy required for breaking of bonds is less than the energy released during formation of bonds. In case of an endothermic reaction, the activation energy of the forward reaction is more than that of backward reaction.

Q. Assertion :Most of the combustion reactions are exothermic. Reason: Products are more stable than reactants are exothermic.

Q. Assertion :All combustion reactions are exothermic. Reason: Enthalpies of products are greater than enthalpies of reactants
