The graph of the reaction pathway will resemble a hill, with the left part of the hill being at a higher level than the right part of the hill. This is due to the fact that the reactants have a higher energy than the products, so the excess energy will be released. The difference in heights of the products and reactants will be equivalent to the difference in energies, which is 87 kJ.
