If a chemical reaction is reversed, what happens to the enthalpy of the reaction?
nataly862011 [7]

Answer:   C. The sign of the enthalpy of the reaction reverses.

Explanation: Enthalpy of a reaction is the net heat absorbed or released  during a chemical reaction.It is represented by \Delta H. It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.

When a chemical reaction is reversed the heat of the reaction changes its sign.

CaCO_3\rightarrow CaO+CO_2   \Delta H=+ve

The decomposition of calcium carbonate is an endothermic reaction as heat is required to break the bonds and thus energy is absorbed.

CaO+CO_2\rightarrow CaCO_3    \Delta H=-ve

When the reaction is reversed, the reaction becomes exothermic as now bonds are getting formed and energy is released.
