ΔH = [tex] H_{Products} - H_{Reactants} [/tex]

ΔH = +ve for Endothermic

ΔH = -ve for Exothermic


An exothermic reaction has reactants that are higher in energy than products because energy is absorbed to form the products.

An endothermic reaction has reactants that are lower in energy than products because energy is released to form the products.

This can be verified with the above equations.
