IB syllabus for first examinations 2016

6.2 - Calculation of enthalpy changes

6.2.1: Calculate the heat change when the temperature of a pure substance is altered. Students should be able to calculate the heat change for a substance given the mass, specific heat and temperature change.


6.2.2: Explain that the enthalpy changes of a reaction relate to the specific quantities of either reactants or product. Enthalpy changes are measured in joules(J) and are often quoted in kJ mol-1 of either a reactant or a product


6.2.3: Analyse experimental data for enthalpy changes of reactions in aqueous solution.


6.2.4: Calculate the enthalpy change for a reaction in aqueous solution using experimental data on temperature changes, quantities of reactants and mass of solution. Enthalpy changes of an acid-base reaction could be investigated.
