CAIE A Level Chemistry 9701 · Reaction kinetics
A student measures the rate of the reaction between two gases at several temperatures above room temperature. The rate increases as the temperature rises.
Suggest two reasons why the rate of this reaction increases when the temperature is raised.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Suggest means: Apply what you know to an unfamiliar situation. There may be more than one acceptable answer. Reason from the principle you have learned to the new context, and say which principle you are using.
