Rates of reaction and equilibrium

Explain factors affecting rates of reaction, collision theory, catalysts and dynamic equilibrium

What you'll learn

  1. 1

    Imagine you're baking a cake. The rate of reaction is how fast the cake cooks — some things make it cook faster, some slower!

  2. 2

    What does 'rate of reaction' mean?

  3. 3

    Drag the slider to see how temperature changes how fast a reaction happens. Hotter = faster!

  4. 4

    Let's work out how concentration affects rate. Imagine a solution with 10 particles — more particles means more collisions!

  5. 5

    What happens to the rate of reaction if you increase concentration?

  6. 6

    Set up a reaction with a catalyst to see how it speeds things up without being used up.

  7. 7

    A catalyst makes a reaction faster. What happens to the catalyst?
