Worksheet: Factors Affecting Heterogeneous Catalysis

In this worksheet, we will practice estimating the diffusion coefficients of reactants over a catalyst and the effects of tortuosity and pore diameter.

Q1:

Which of the following is not a mechanism by which a catalyst increases the rate of a reaction?

  • AWeakening bonds in reactants
  • BReacting with reactants to form a less stable intermediate
  • CIonizing reactants
  • DIncreasing the polarity of reactants
  • EIncreasing the average kinetic energy of reactants
