Irreversible and Reversible Reactions 0.0 / 5 ? ChemistryEquilibriumRate of reactionGCSEAQA Created by: Iss WhizzCreated on: 24-01-20 14:32 What is a reversible reaction? When products react to make the original reactants again. 1 of 13 An example of a reversible reaction. Heating ammonium chloride. 2 of 13 What is a irreversible reaction? A reaction that cannot be changed back to its original state. 3 of 13 An example of a irreversible reaction. Combustion 4 of 13 What happens in reversible reaction? There are two key reactions one is endothermic and the other is exothermic. 5 of 13 What happens in a closed system? The rate of the forward and reverse reactions is equal at equilibrium. 6 of 13 What happens when you change the reaction conditions? It can change the amounts of products and reactants in a reaction mixture at equilibrium. 7 of 13 What can affect reversible reactions? Pressure 8 of 13 What does increasing the temperature do? It favours the endothermic reaction. 9 of 13 What does decreasing the temperature do? It favours the exothermic reaction. 10 of 13 What is a catalyst? A substance that speeds up a reaction. 11 of 13 What is the minimum amount of energy that particles must have before they can react? Activation energy 12 of 13 What is the collision theory? When suitable particles of the reaction hit each other. 13 of 13
