Complete lessons and workbook
Content
- Know that chemical reactions in which heat energy is given out are described as exothermic and those in which heat energy is taken in are endothermic
- Describe simple calorimetry experiments for reactions such as
combustion, displacement, dissolving and neutralisation - Calculate the heat energy from a measured temperature change
using the expression Q = mcΔT - Calculate molar enthalpy change (ΔH ) from heat energy change Q
- Draw and explain energy level diagrams to represent
exothermic and endothermic reactions - Know that bond-breaking is an endothermic process and that
bond-making is exothermic - Use bond energies to calculate the enthalpy change during a
chemical reaction
