a i. Explain whether the reaction below is an example of heterogeneous or homogeneous catalysis:

ii. Explain how a catalyst increases the rate of reaction in terms of activation energy and the distribution of molecular energies in a sample of reactants.

b. Enzymes are used in the biotechnology industry. They are far more efficient than traditional catalysts used in industrial processes. What would be the benefits of using enzymes instead of traditional catalysts in the industrial production of a chemical?

c. Draw an energy profile diagram to show a typical uncatalysed reaction and an enzyme-catalysed reaction. On your diagram show:

i. The activation energy for the catalysed and uncatalysed reactions

ii. The enzyme, substrate and product and enzyme–substrate intermediate.
