Rates of reaction

Question 1

How can we compare the reaction rate of different experiments?

Answer 1

Measure the volume of gas collected over a given time.

Question 2

What 4 factors will increase the rate of a reaction?

Answer 2

1. Increasing the temperature
2. Increasing the concentration
3. Decreasing the particle size
4. Using a catalyst

Question 3

How do we calculate average rate?

Answer 3

Question 4

What 2 benefits are there for using a catalyst?

Answer 4

1. Increases reaction rate
2. Can be re-used (doesn’t take part in reaction)
