Answer: Option E) the products have less potential energy than the reactants
Explanation:
Though the actual graph is not displayed, but, whenever reactants occupy a position higher than the product on the graph of reaction coordinate vs time taken, it means the reactants (AB+CD) have molecules with higher energy bonds than the products AC +BD
Thus, the reaction of AB + CD to yield AC+BD will occur spontaneously with the release of energy.
