Hydrochloric acid and sodium hydroxide react to produce water and sodium chloride in an endothermic reaction. Which statement must be true of the reaction?

Responses-

a) The bond energy used to break the bonds in hydrochloric acid and sodium hydroxide is less than the energy released to form the bonds in water and sodium chloride.

b) The total bond energy of water and sodium chloride is greater than the total bond energy of hydrochloric acid and sodium hydroxide.

c) More bond energy is absorbed on the reactants side than is released on the products side.

d) The energy of each bond in water and sodium chloride is greater than the energy of each bond in hydrochloric acid and sodium hydroxide.

c) More bond energy is absorbed on the reactants side than is released on the products side. (Since it is an endothermic reaction, energy is absorbed rather than released, and therefore less energy is released in forming the products than is absorbed in breaking the bonds of the reactants.)
