Consider the following energy profile diagram and use it to answer the question that follows

The enthalpy change of the reaction is------------

E\(_{A}\)
E\(_{B}\)
E\(_{C}\)
E\(_{D}\)

Explanation

Enthalpy change, ΔH = ΔH\(_{product}\) - ΔH\(_{reactant}\)

From the diagram E\(_D\) represents the enthalpy change, ΔH.
