Energy (OCR A Level Chemistry)

6 Full Lesson Bundle covering the first 6 chapters in the OCR A Level Chemistry Chapter on Energy **Lesson 1: Lattice Enthalpy** 1. Explain the term lattice enthalpy 2. Understand the factors that determine the size of lattice enthalpy 3. Explain the terms standard enthalpy change of formation and first ionisation energy **Lesson 2: Born-Haber Cycles** 1. Construct Born Haber Cycle diagrams for ionic compounds from enthalpy change values 2. Calculate the value for lattice enthalpy from Born Haber Cycle diagrams 3. Calculate other enthalpy change values from Born Haber Cycle diagrams **Lesson 3: Enthalpy Changes of Solution & Hydration** 1. Define the terms enthalpy change of solution and hydration 2. Construct enthalpy cycles using the enthalpy change of solution of a simple ionic solid 3. Qualitatively explain the effect of ionic charge and ionic radius on the exothermic value of lattice enthalpy and enthalpy change of hydration **Lesson 4: Entropy** 1. Know that entropy is a measure of the dispersal of energy in a system, which is greater the more disordered a system 2. Explain the difference in entropy of solids, liquids and gases 3. Calculate the entropy change of a reactant based on the entropies provided for the reactants and products **Lesson 5: Gibbs Free Energy (Part 1)** 1. Explain that the feasibility of a process depends upon ΔG being negative which in turn depends upon ΔS, ΔH and the T of the system 2. Recall the Gibbs’ Equation and calculate ΔG, ΔH, ΔS or T 3.Calculate ΔG, ΔH, ΔS or T using the Gibbs’ Equation **Lesson 6: Gibbs Free Energy (Part 2)** 1. Explain that the feasibility of a process depends upon ΔG being negative which in turn depends upon ΔS, ΔH and the T of the system 2. Recall the Gibbs’ Equation and calculate ΔG, ΔH, ΔS or 3. Calculate ΔG, ΔH, ΔS or T using the Gibbs’ Equation The teacher will be able to check students have met these learning objectives through starter activities, discussion questions, mini AfL tasks and practice questions for students to complete ***Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above***
