Factors Affecting Reaction Rates

Investigate how temperature, concentration, pressure, and surface area influence the speed of chemical reactions. Understand the practical implications of these factors in laboratory and industrial settings.

National Curriculum Attainment TargetsDfE GCSE specifications Chemistry Key Stage 4: The rate and extent of chemical changeRecall how changing these factors affects the rate of chemical reactions: the concentrations of reactants in solution, the pressure of reacting gases, the surface area of solid reactants, the temperature and the presence of catalysts.

About This Topic
