N2(g) + 3H2(g) → 2NH3(g); ΔH = -91.8 kJ Consider the thermochemical equation for the synthesis of ammonia. Which statement is true? A) Negative enthalpy indicates that energy is required to complete the reaction. B) Negative enthalpy indicates a decrease in potential energy and an endothermic reaction. C) Enthalpy is negative indicating that energy is released so this is an exothermic reaction. D) Enthalpy is negative indicating that there is an energy deficit; the reaction is incomplete.

The energy of -91.8 kJ in the reaction equation shows that energy is released so this is an exothermic reaction.

What is a thermochemical equation?

A thermochemical equation is one which just does not only show the reactants and products but also shows the energy absorbed or emitted in the reaction.

We can see from the thermochemical equation; N2(g) + 3H2(g) → 2NH3(g); ΔH = -91.8 kJ that the negative enthalpy implies that  energy is released so this is an exothermic reaction.
