🎯 Exam Focus: Factors Affecting Rate
very-high Explain questions (4-6 marks): For temperature questions, ALWAYS mention both effects: faster movement AND more exceed activation energy. One sentence for each.
very-high Graph comparison (3-4 marks): Interpret graphs showing different conditions — steepness, final amount, time to finish.
high Catalyst questions (2-3 marks): Explain by saying "lowers activation energy" not "provides energy to particles".
Key phrase to earn full marks: "...therefore there are more successful collisions per second, so the rate increases."
