Each transition state in below diagram should be marked with double dagger ( † † ) . Concept introduction: Energetics of a reaction describes the energy associated with different components during the process of reaction. Energy diagram is a plot of energy along Y axis and reaction coordinate along X axis. Reaction proceeds when the reactant molecules collide and have proper orientation. The pathway from reactant to product involves transition state. Transition state is a hypothetical statewhich gives clear picture of the orientation of reactant molecules during collision that is a process of the bonds formed and broken during the reaction. Transition state is highest energy state of a reaction.

Question

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 ovie
