A-Level CAIE Chemistry AS 8.3.1—And use the terms catalyst and catalysis Question Bank

• Explain and use the terms catalyst and catalysis:

- (a) to explain that, with a catalyst, a reaction has a different mechanism, i.e. one of lower activation energy

- (b) to explain this catalytic effect in terms of the Boltzmann distribution

- (c) to construct and interpret a reaction pathway diagram for a reaction in the presence and absence of an effective catalyst
