Rate Equations (AQA)

6 full lesson bundle covering the chapter: Rate Equations from the AQA A Level Chemistry Specification.

Lesson 1: Order of Reactants

LO1: To recall the terms rate of reaction, order, overall order and rate constant
LO2: To describe how orders of reactants affect the rate of a reaction
LO3: To calculate the overall order of a reaction

Lesson 2: The Rate Equation

LO1: To determine the order of a reactant from experimental data
LO2: To calculate the rate constant, K, from a rate equation
LO3: To calculate the units of the rate constant

Lesson 3: Concentration-Time Graphs (Part 1)

LO1: To know the techniques and procedures used to investigate reaction rates
LO2: To calculate reaction rates using gradients from concentration-time graphs
LO3: To deduce zero & first order reactants from concentration-time graphs
LO4: To calculate the rate constant of a first order reactant using their half-life

Note: Concentration-Time Graphs (Part 2) is not applicable for the AQA specification

Lesson 4: Initial Rates and Clock Reactions

LO1: To determine the rate constant for a first order reaction from the gradient of a rate- concentration graph
LO2: To understand how rate-concentration graphs are created
LO3: To explain how clock reactions are used to determine initial rates of reactions

Lesson 5: The Rate Determining Step

LO1: To explain and use the term rate determining step
LO2: To deduce possible steps in a reaction mechanism from the rate equation and the balanced equation for the overall reaction
LO3: To predict the rate equation that is consistent with the rate determining step

Lesson 6: The Arrhenius Equation

LO1: Explain qualitatively the effect of temperature change on a rate constant,k, and hence the rate of a reaction
LO2: To Know the exponential relationship between the rate constant, k and temperature, T given by the Arrhenius equation, k = Ae–Ea/RT
LO3: Determine Ea and A graphically using InK = -Ea/RT+ InA derived from the Arrhenius equation

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
