Problem

If a reaction

\text{A} + 2\text{B} \rightarrow \text{products}

has the rate equation

\text{rate} = k[\text{A}]^2

, deduce the rates in experiments 2 and 3 in the table below.

Experiment	$[\text{A}] / \text{mol dm}^{-3}$	$[\text{B}] / \text{mol dm}^{-3}$	Rate / $\text{mol dm}^{-3} \text{s}^{-1}$
1	0.01	0.01	$3.8 \times 10^{-3}$
2	0.02	0.01
3	0.02	0.02
