The Rate of Reaction

Question 1

what is a slow reaction?

Answer 1

A slow reaction is a low rate with unreactive materials such as rusting iron

Question 2

what is a moderate reaction?

Answer 2

A moderate speed reaction is a quite low reaction often between a metal reacting with acid to produce a gentle stream of bubbles

Question 3

what is a fast reaction?

Answer 3

A fast reaction is the quickest and is an explosion

Question 4

what four things affect the rate of reaction?

Answer 4

1. Temperature
2. Concentration (or pressure for gases)
3. Catalyst
4. Surface area of solids (of size of solid pieces)

Question 5

how do you work out the rate of reaction?

Answer 5

Amount of product used or amount of product formed divided by time taken

Question 6

what are the three ways of measuring the rate of reaction?

Answer 6

1. Precipitation
2. Change in mass
3. The volume of gas given off
