Question

Most reactions occur by a series of steps. The energy profile for a certain reaction that proceeds by a two-step mechanism is shown below. 2 1 Reaction coordinate In regard to the energy profile, identify the following. (a) The positions of reactants and products reaction coordinate for reactants 1 reaction coordinate for products 3 (b) The activation energy for the overall reaction. (Enter your answers in increasing numerical order.) the energy difference between reaction coordinatesSelect and-Select (c) AE for the reaction. the energy difference between reaction coordinates--Select v and --Select-- v (d) The point on the plot that represents the energy of the intermediate in the two-step reaction reaction coordinate for the intermediateSelect-- (e) Which step in the mechanism for this reaction is rate determining, the first or second step? the first step the second step not enough information is given to make this determination Explain. (Select all that apply.) Since the second hump in the reaction is at the highest energy, the second step has the smallest activation energy and will be the rate-determining step. In a mechanism, the rate of the slowest step determines the rate of the reaction The activation energy for the slowest step will be the largest energy barrier that the reaction must overcome. In a mechanism, the rate of the reaction is determined by the total energy barrier encountered for the overall reaction
