. It is negative for exothermic reactions in which heat is released and is positive for endothermic reactions in which heat is absorbed.

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

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