The data in the table given below was obtained in a series of experiments on the rate of the reaction between compounds [A] and [B] at a constant temperature:

Experiment	The initial concentration of [A] $\text{mol dm}^{-3}$	The initial concentration of [B] $\text{mol dm}^{-3}$	Initial rate $\text{mol dm}^{-3}\text{ s}^{-1}$
1	$0\cdot15$	$0\cdot30$	$1\cdot10 \times 10^{-4}$
2	$0\cdot30$	$0\cdot30$	$4\cdot40 \times 10^{-4}$
3	$0\cdot60$	$0\cdot15$	$8\cdot80 \times 10^{-4}$

Show how this data can be used to deduce the rate expression for the reaction between [A] and [B].
