AS Chemistry: Kinetics (OCR)

3 Full Lesson Bundle which covers the Kinetics chapter from the OCR AS Level Chemistry Specification (may also suitable for the AQA and Edexcel Spec- see Learning Objectives below to confirm)

Lesson 1: Collision Theory & Rates of Reaction

**1. To explain the effect of concentration (including pressure of gases only) on the rate of reaction in terms of the frequency of collisions
**2. To calculate the rate of reaction using the gradients of a concentration-time graph
**3. To describe the techniques and procedures used to investigate reaction rates including the measurement of mass, gas volumes and concentration

Lesson 2: Catalysts

**1. To explain the effect of concentration (including pressure of gases only) on the rate of reaction in terms of the frequency of collisions
**2. To calculate the rate of reaction using the gradients of a concentration-time graph
**3. To describe the techniques and procedures used to investigate reaction rates including the measurement of mass, gas volumes and concentration

Lesson 3: The Boltzmann Distribution

**1. To draw a labelled diagram of the Boltzmann distribution
**2. To explain qualitatively the Boltzmann distribution and its relationship with activation energy
**3. To explain how temperature changes and catalytic behaviour effect the proportion of molecules exceeding the activation energy and hence the reaction rate using Boltzmann distributions

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 reviewed during these scenarios outlined above
