CAIE A Level Chemistry 9701 · Reaction kinetics
The reaction between bromate(V) ions and bromide ions in acid solution has an activation energy of 50 kJ mol. Explain, in terms of the Boltzmann distribution and the concept of activation energy, why increasing the temperature of the reaction mixture increases the rate of reaction.
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.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
