Rate equation, rate constants and orders of reaction A level Chemistry lesson with questions and answers. Deriving units of rate constant plus the initial rate method for determining rate equation with worked examples. This is a Year 13 A level lesson for Edexcel and Edexcel International. All the slides in this lesson are fully animated and include answers to every mini plenary question and exam question. The breakdown of the slides (which are best opened on Microsoft PowerPoint) is as follows:

Slide 1 - Title and 5-minute starter. The starter is a grid of four questions entitled ‘last week, last lesson, today’s learning and future learning’. Use this generic slide for all of your lessons by simply changing the questions and the answers each time.
Slide 2 - Lesson objectives (see thumbnail image)
Slide 3 – definition of rate of reaction, with a graph showing change of concentration of reactant and product over time
Slide 4 – discussion of units of rate of reaction (this will be very important for working out units of rate constant later)
Slide 5 – Mini plenary (learning pit-stop). Questions pop on to the screen when you click. Cold call students or use a random name generator to elicit a response.
Slide 6 – Introduction to the concept of a rate equation
Slide 7 – student-friendly data is presented in a table (bananas and boxes) which shows direct proportionality
Slide 8 – students will be shown how to write an equation for the number of bananas to boxes including a proportionality constant
Slide 9 – students are shown how a rate expression of proportionality to concentration of reactant A can be converted into a rate equation including the rate constant, k. The bananas and boxes example will make the transition seamless!
Slide 10 – definition of order (with respect to a reactant)
Slide 11 – zero order explained (with rate-concentration graph)
Slide 12 - first order explained (with rate-concentration graph)
Slide 13 - second order explained (with rate-concentration graph)
Slide 14 – explanation of how overall order of a reaction is calculated
Slides 15 – 16: explanation of how units for rate constant are calculated with a worked example
Slide 17 - slide just explaining rules of exponents (mainly for students not studying A level Mathematics)
