This excellent resource contains 2-3 lessons which cover Chemical energetics. Each lesson contains a starter activity with answers, notes, research tasks, questions with answers, practicals. The lessons include the follwing content: Core: State that an exothermic reaction transfers thermal energy to the surroundings leading to an increase in the temperature of the surroundings State that an endothermic reaction takes in thermal energy from the surroundings leading to a decrease in the temperature of the surroundings Interpret reaction pathway diagrams showing exothermic and endothermic reactions Supplement: State that the transfer of thermal energy during a reaction is called the enthalpy change, ∆H, of the reaction. ∆H is negative for exothermic reactions and positive for endothermic reactions Define activation energy, Ea , as the minimum energy that colliding particles must have to react Draw and label reaction pathway diagrams for exothermic and endothermic reactions using information provided, to include: (a) reactants (b) products © enthalpy change of the reaction, ∆H (d) activation energy, Ea State that bond breaking is an endothermic process and bond making is an exothermic process and explain the enthalpy change of a reaction in terms of bond breaking and bond making Calculate the enthalpy change of a reaction using bond energies **This resource can be used to teach IGCSE Chemistry (C5) or iGCSE Co-ordinated science (C6). **
