Rates of reaction | practical videos | 16–18 students
By Dorothy Warren, David Paterson and Sandrine Bouchelkia
Video and supporting resources, includes an initial rate (iodine clock reaction) and continuous monitoring method (volume of gas)
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.
