Rates of Reaction Revision 0.0 / 5 ? ChemistryRate of reactionGCSEAQA Created by: TheTominatorCreated on: 29-11-17 09:21 What is Oxidation? When the metal loses electrons in a displacement 1 of 13 What is Reduction? When the metal gains electrons in a displacement 2 of 13 What is OILRIG? Oxidation Is Loss, Reduction Is Gain 3 of 13 What is an Exothermic Reaction? When Energy is given out (Gets Hot) 4 of 13 What is an Endothermic Reaction? When Energy is taken in (Cools down or needs heating) 5 of 13 What is an example of an Exothermic Reaction? Hydrogen Baloon - Small explosion and heat is given out 6 of 13 What is an example of an Endothermic Reaction? Heating Copper Carbonate - Heat is needed to create a reaction 7 of 13 How do you work out Rate of Reaction? Rate of Reaction = Change in quantity of reactant or product / Time 8 of 13 How does temperature affect Rates of Reaction? The warmer a substance is, the faster it will react. 9 of 13 How does concentration affect Rates of Reaction? The more concentrate the reactant, the faster the reaction. 10 of 13 How do catalysts affect Rates of Reaction? Catalysts speed up reactions. They arent used up and can catalyse again. 11 of 13 How does particle size affect Rates of Reaction? The smaller the particle, the larger the surface area meaning that the reaction has a larger area to occur. 12 of 13 What are acids? Chemicals with a Ph Level less than 7. Corrosive 13 of 13
