Using the method of initial rates, determine the rate law and rate constant, k for the following reaction:
$A_2(g) + B_2(g) \rightleftharpoons 2AB(g)$
\begin{tabular}{|c|c|c|c|}
\hline
Trial & $[A_2]$ M & $[B_2]$ M & Rate M/min \\
\hline
1 & 0.00501 & 0.0100 & $3.01 \times 10^{-3}$ \\
2 & 0.0100 & 0.0102 & $1.20 \times 10^{-2}$ \\
3 & 0.0100 & 0.0201 & $2.39 \times 10^{-2}$ \\
\hline
