Question

12. If a reaction is exothermic,

a) It takes more energy to break the bonds of the reactants than is released when the bonds in
the products are formed
b) More energy is released when the bonds in the products are formed than is used to break
the bonds in the reactants
c) The same amount of energy is used to break the bonds of the reactants as is
released when the bonds in the products are formed
d) The temperature goes down

Answer 1

In the case of an exothermic reaction, the reactants are at a higher energy level as compared to the products, as shown below in the energy diagram. In other words, the products are more stable than the reactants. Overall Δ H ΔH ΔH for the reaction is negative, i.e., energy is released in the form of heat.
