1

What is the rate of a reaction?

change in concentration/change in time

2

What is the overall order of a reaction?

The sum of all the individual orders of the reactants

3

What is the rate equation?

rate = k[A]m[B]n

4

What is the half-life of a reactant?

The time taken for a reactant's concentration to decrease by half

5

How do you find the rate of a reaction at any time using a graph

Draw a tangent and find the gradient

6

How can you calculate k from half life?

K = ln2/T1/2

7

How do you calculate k from a rate-concentration graph of a first order reactant?

Gradient of the straight line

8

What is the rate-determining step?

The slowest step in the reaction mechanism of a multi-step reaction
