CAIE A Level Chemistry 9701 · Reaction kinetics
A reaction has an activation energy of . The reaction is carried out at two temperatures, and , where .
Compare the Boltzmann distributions of molecular energies at these two temperatures, and use this to explain why the rate of reaction is faster at .
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Compare means: Give similarities or differences between two things, and say which side each point belongs to. Write each point as a pair, for example: A is X, whereas B is Y. Two separate descriptions rarely earn the marks.
