AQA GCSE Chemistry 2.4 Rates of reaction 0.0 / 5 ? ChemistryRates of reactionGCSEAQA Created by: Shaye :)Created on: 14-05-14 18:53 What factors affect the rate of a reaction? Temperature, the presence of a catalyst, concentration, pressure and surface area 1 of 5 How do you find the rate of a chemical reaction? Amount of reactant used / time 2 of 5 What is the activation energy? The minimum amount of energy particles must have to react 3 of 5 Why does increasing temperature increase rate of reaction? The particles have more energy and so have more energetic and successful collisions 4 of 5 Why are catalysts useful in industry? They are not used up in reactions so can be used again, and saves energy and therefore saves costs 5 of 5
