Which factors affect thermal stability? What is lesser and greater decomposition? Why does thermal stability increase down group 1 and 2? All this and more covered in this comprehensive lesson with questions and answers! This is a Year 12 A level lesson for Edexcel International Unit 2 – WCH12, 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 – meaning of the key word thermal stability, and the difference between high and low thermal stability
Slide 4 – Thermal decomposition of group 1 nitrates, including lesser and greater decomposition with example word and symbol equations
Slide 5 – Thermal decomposition of group 2 nitrates, including lesser and greater decomposition with example word and symbol equations
Slide 6 – Observations and key points for the thermal decomposition of group 1 and group 2 nitrates
Slide 7 – Thermal decomposition of group 1 carbonates, including lesser and greater decomposition with example word and symbol equations
Slide 8 – Thermal decomposition of group 2 carbonates, including lesser and greater decomposition with example word and symbol equations
Slide 9 - Observations and key points for the thermal decomposition of group 1 and group 2 carbonates
Slide 10 – learning pit-stop to check students’ learning. A series of questions of increasing difficulty, with the stretch and challenge (S+C) being the hardest. Answers animate onto the screen when you click
Slide 11 – Summary slide of the trends in thermal decomposition of nitrates and carbonates in group 1 and 2
Slide 12 – Hinge question: Why does thermal stability increase down groups 1 and 2 for nitrates and carbonates?
Slides 13 – 15: Explanation to the question from the previous slide
Slides 16 – 18: Exam questions with mark scheme answers (included with the purchase of this resource)
