Answer:
D
Knowledge points:
8.2.1 define activation energy, $ E_{\mathrm{a}}$, as the minimum energy required for a collision to be effective
8.2.2 sketch and use the Boltzmann distribution to explain the significance of activation energy
8.2.3 explain qualitatively, in terms both of the Boltzmann distribution and of frequency of effective collisions, the effect of temperature change on the rate of a reaction
