Rates of reaction and equilibrium
Explain factors affecting rate of reaction (collision theory), catalysts, and reversible reactions/dynamic equilibrium
What you'll learn
- 1
Think about making a cup of tea 🫖 — the hotter the water, the faster the tea bag releases its flavour. That's a rate of reaction!
- 2
What does 'rate of reaction' mean?
- 3
Let's work out how temperature affects a reaction between fizzy tablets and water 💊💧
- 4
Watch the particles collide — hotter means more energy!
- 5
Why does a higher temperature make a reaction faster?
- 6
Now try increasing concentration — more particles means more collisions per second!
- 7
What happens to the rate if you use a bigger piece of solid (less surface area)?
