Rates of reaction | practical videos | 16–18 students

Video and supporting resources to support practical work on rates of reaction, includes both an initial rate and continuous monitoring method.

Investigate rates of reaction with two experiments for learners on A-level and equivalent 16–18 courses. These experiments provide learners with the opportunity to monitor the rate of reaction and identify the effects of changing temperature and concentration, using both initial rate and continuous monitoring methods. Additional resources including pause-and-think questions with answers, teacher notes, technician notes, intended outcomes and a follow-up worksheet are provided to support your teaching.
