45 study the following reaction energy diagram:

1i. Draw an energy vs reaction coordinate diagram to illustrate a reaction in which the energy of the products is greater than the energy of the reactants. Label all quantities as per Fig. 1. See diagram (3) in sample exercise 14.10 on pg 595 of Brown and LeMay, 11th ed. Which of the following statements is not true? A) Two reactions can have identical values for DH° but very different Ea values. B) The larger the activation energy, the slower the reaction. C) DH° determines the height of the energy barrier. D) The lower the activation energy, the faster the reaction.

It decreases the kinetic energy of reactants, enabling them to undergo chemical change more easily. Correct Answer: By lowering the activation energy, an enzyme increases the rate of the reaction. Review B. 4. Consider the following energy diagram for a chemical reaction.

Given the reaction at ... Which of the following statements correctly describe the key aspects of drawing a reaction energy diagram. For an exothermic reaction the energy of the products is less than the energy of the reactants.

Explanation: The fully filled in reaction coordinate diagram is displayed below. The arrow marked in the question represents the activation energy, which is the energy barrier that must be overcome in order for the reactants to form products. This reaction is also exothermic because the energy of the products is lower than that of the reactants. Here the energy of the reactant is less than the product i.e ; it is an endothermic reaction. Hence, in this reaction the energy is absorbed. Her …. View the full answer.
