Arrhenius equation can be used to calculate activation energy for a reaction – students will learn in this lesson! Natural logarithms, Arrhenius plots, finding activation energy from the gradient and the pre-exponential factor from the Y intercept are all explored in this lesson. This is a Year 13 A level lesson for Edexcel International Unit 4 – WCH14, but it can also be used for all UK exam boards. 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 – Introduction to logarithms with some simple examples
Slide 4 – full explanation of natural logarithms, including Euler’s number
Slide 5 – transition slide
Slides 6 – 8: Arrhenius equation is introduced, with exposition of all the symbols and units
Slides 9 – 10: A basic approach to the Arrhenius equation, explaining how a high temperature and high Ea affects k
Slides 11 – 12: A more detailed look at the Arrhenius equation, rearranging to make Ea the subject
Slide 13 – Worked example 1: Finding the activation energy by calculation
Slide 14 – 15: Printable format of worked example 1
Slide 16 – 22: detailed explanation, with examples, of how to find the activation energy and the pre-exponential factor graphically
Slides 23 -29 : Exam questions with mark scheme answers (included as a word document with this resource)

Edexcel International A level Chemistry - lessons with questions and answers | Topic 11 | Kinetics

Bundle is comprised of 6 PowerPoint lessons covering Topic 11 - Kinetics for the Edexcel International A level Chemistry course, Unit 4 – WCH14, but it can be used for all UK exam boards which have a Kinetics unit. The PowerPoints are as follows: 1. Techniques for measuring rate of reaction 2. Rate Equation, Rate Constant and Orders of Reaction 3. Determining Orders of Reaction (including the Continuous method for determining rate equation and half-life) 4. Rate Equations and Reaction Mechanisms 5. Activation Energy and Catalysis (Homogeneous, Heterogeneous and Autocatalysis) 6. Arrhenius Equation (solving Activation Energy by calculation and graphically) Each lesson is exactly that . . . a lesson. There is a starter slide, lesson objectives slide, introduction of new knowledge slides, worked examples and then opportunities for students to try independent practice through mini plenary tasks comprised of several questions of graded difficulties. Questions are interspersed through the lessons at regular intervals and always have answers that animate on to the screen when you click. THESE ARE NOT THE INFORMATION ONLY TYPE SLIDES THAT SOME PEOPLE SELL, which are useless for delivering a lesson. We are a team of teachers, and these lessons have been made by actual Chemistry teachers who currently teach in secondary schools in England. We know exactly what you need, trust me. Some lessons have exam questions included as word documents which were made using Exam wizard. Where this is the case, the mark scheme is at the end of the exam question and the answers have been screen shotted and pasted into the PowerPoint at the end. All the slides in every lesson are fully animated and include answers to every mini plenary question and exam question. Please note: core practicals 9a, 9b and 10 have not been included, as we are preparing a separate resource for all the core practicals. Watch this space!
