- 3. A reaction occurs in two steps. Both steps are exothermic, and the second step is the rate determining step. Draw an energy diagram showing energy versus reaction coordinate. Label the reactants, products, intermediates, and transition states. According to the Hammond postulate, will the second transition state resemble the intermediates or the products? ent oviearrow_forwardConsider the following energy diagram. a.How many steps are involved in this reaction? b. Label ΔHo and Ea for each step, and label ΔHooverall. c.Label each transition state. d.Which point on the graph corresponds to a reactive intermediate? e.Which step is rate-determining? f. Is the overall reaction endothermic or exothermic?arrow_forwardBased on the reaction and its DH° CI -OH rxn, why is this reaction exothermic? OH AH-110.6 kJ/mole the product bonds are stronger than the reactant bonds because the product bonds are more polar the product bonds are weaker than the reactant bonds because the product bonds are more polar the product bonds are weaker than the reactant bonds because the product bonds are less polar the product bonds are stronger than the reactant bonds because the product bonds are less polararrow_forward
