Rate Graphs

Question 1

How do you calculate the rate of reaction at a specific time?

Answer 1

1) draw a tangent from where the time is
2) calculate the gradient (rise / run)

Question 2

What does a rate graph look like?

Answer 2

1) At first there is a steep gradient, meaning the rate of reaction is fast
2) The gradient decreases as rate of reaction slows down due to reactants being used
3) The line plateaus as all reactants have been used up and the reaction has stopped
