What is a catalyst and what can they be used for? C2 Topic 5: Chemical Reactions This topic looks at: Exothermic and endothermic reactions Factors that affect rates of reaction Rates of Reaction. Using the particle model explain how the following affect the rate of reaction using diagrams. Concentration Surface Area Temperature Catalyst What happens to the temperature in Endothermic reaction? Exothermic reaction? Energy Diagrams – Draw on energy diagrams to represent, explain using bond breaking and formation EXOTHERMIC ENDOTHERMIC Keywords: temperature, bond breaking, bond making What is a catalyst and what can they be used for?
