Question

Consider the following energy diagram for a reaction. 
-Which letter represents the net energy change of the reaction?

Quizplus · Accepted Answer

The net energy change of the reaction is the difference between the energy of the products and the energy of the reactants. In this diagram, the energy of the reactants is shown on the left side and the energy of the products is shown on the right side. The difference between the two is represented by the vertical distance between them. In this case, the vertical distance between the reactants and products is greatest at point D, indicating the largest net energy change for the reaction.
