Topic 5: Energetics 5.1 Exothermic and endothermic reactions 5.1.1 Define the terms exothermic reaction, endothermica reaction and standard enthalpy change of reaction Standard enthalpy change: heat energy transferred under standard conditions 5.1.2 State that combustion and neutralization are exothermic processes 5.1.3 Apply the relationship between temperature change, enthalpy change and the classification of a reaction as endothermic or exothermic Exothermic: Produces heat; negative value for H Endothermic: Absorbs heat; positive value for H 5.1.4 Deduce, form a enthalpy level diagram, the relative stabilities of reactants and products and the sign of the enthalpy change for the reaction When product is higher than reactants: less stable and +ve enthalpy When product is lower than reactants: stable and –ve enthalpy 5.2 Calculation of enthalpy changes 5.2.1 Calculate the heat energy change when the temperature of a pure substance is changed Q=mcT 5.2.2 Design suitable experimental procedures for measuring the heat energy changes of reaction
