5.1 - Exothermic and endothermic reactions
5.1.1: Define the terms exothermic reaction, endothermic reaction and standard enthalpy change of reaction (? HØ).
Standard enthalpy change is the heat transferred under standard conditions - pressure 101,3kPa, temperature 298K. Only ? H can be measured, not H for the initial or final state of a system
5.1.2: State that combustion and neutralisation are exothermic processes
5.1.3: Apply the relationship between temperature change, enthalpy change adn the classification of a reaction as exothermic or endothermic
5.1.4: Deduce from an enthalpy level diagram the relative stabilities of reactants and products and the sign of the enthalpy change for the reaction.
