5 x 1 hour lessons

This module explores the factors affecting how fast reactions occur. You’ll learn how to measure rates, define and use rate equations, and understand the effect of concentration, temperature, and catalysts. The module includes calculating rate constants and analysing rate data graphically and numerically.

By the end of this module you will be able to: • define rate of reaction and explain methods of measuring it • describe the effect of temperature, concentration, surface area, and catalysts on rate • explain collision theory and the role of activation energy • sketch and interpret Maxwell–Boltzmann distributions • derive rate equations from experimental data • calculate rate constants and use units to verify order • analyse rate–concentration graphs for first and second order reactions • use initial rate and clock methods to determine rate equations • describe and interpret multi-step reaction mechanisms
