Reacting particle model 2.5 / 5 based on 3 ratings ? ChemistryEnergy of reactions/Exothermic and endothermic reactionsGCSEAQA Created by: Belle StoreyCreated on: 10-01-13 20:10 What does the rate of reaction depend on? the number of successful collisions between the reacting particles(collision frequency) 1 of 5 What three ways can rate of reaction be increased by? the concentration, raising the temperature, raising the pressure 2 of 5 How does concentration increase rate of reaction? the particles become more crowded. this increases the number of collisions between reacting particles. 3 of 5 how does raising the temperature increase rate of reaction? the particles gain kinetic energy and move around more quickly 4 of 5 how does raising the pressure increase rate of reaction? forces particles closer together 5 of 5
