AQA Chemistry Energy Level Diagrams 2.0 / 5 based on 1 rating ? ChemistryEnergy of reactions/Exothermic and endothermic reactionsGCSEAQA Created by: BenjaminCreated on: 01-04-13 16:06 What do energy level diagrams show us? The relative amounts of energy contained in the reactants and products 1 of 5 What is this energy measured in? KJ/Mol 2 of 5 Are the products at a higher or lower energy level than the reactants in an exothermic reaction? Products are at a LOWER energy level than the reactants 3 of 5 In an endothermic reaction, are the products at a higher or lower energy level than the reactants? Products are at a HIGHER energy level than the reactants 4 of 5 The minimum amount of energy needed for molecules to collide (which kicks off a reaction) is called... The activation energy 5 of 5
