**Transcription and Explanation for Educational Website**---**Question:**Use the labels on the potential energy diagram below (a–f) to answer the following questions.**Diagram Explanation:**The diagram is a potential energy graph which plots potential energy on the y-axis versus the reaction coordinate (from X + Y to Z) on the x-axis.- There are markers labeled (a) through (f) on the vertical lines and along the curve: - (a) indicates the potential energy difference between the reactants and the lowest point on the graph. - (b) marks the potential energy of the reactants (X + Y). - (c) is the height from the reactant energy (b) up to the peak of the curve (activation energy). - (d) marks the peak of the curve, indicating the transition state. - (e) shows the potential energy difference between the reactants and the products. - (f) indicates the potential energy of the products (Z).**Questions:**i. Which letter on the diagram represents the potential energy of the products? __ii. Which letter indicates the potential energy of the reactants? __iii. Which letter indicates the activation energy? __iv. Which letter indicates the overall free energy change of the reaction? __v. Is the reaction exergonic or endergonic? __vi. Which letter indicates the activation energy of the reverse reaction? __---

To label the letters , we would use the definitions of all these terms for which the letters have to be assign.1.) Potential energy of products: This is the value of energy acquired by products. Product is Z , so energy of products is represented by Letter (e) . 2.) Potential energy of Reactants : This is the value of energy acquired by reactants. Reactants are X + Y, so energy of Reactants is represented by letter (a) 3.) Activation energy : It is the minimum value of energy that is required by reactants so that it can change to products . This is the difference in energy of Transition state and Reactants . So, activation energy is represented by letter (b) 4.) Overall free energy change of reaction : It is difference in energy of Reactants and products . So, overall free energy change of reaction is represented by letter (f) 5.) From this energy profile diagram, we can see that energy of products is higher than reactants. This suggests that in this reaction energy is absorbed . So, reaction is endergonic. 6.) Activation energy of reverse reaction: This is the difference of energy of transition state and products . So, activation energy of reverse reaction is represented by letter (d)
