The kinetic data for the reaction

\text{A}(g)+2\text{B}(g)\rightarrow\text{C}(g)

are given below at

300\,\text{K}

Experiment no.	$[\text{A}]\,/\,\text{M}$	$[\text{B}]\,/\,\text{M}$	Initial rate $\,/\,\text{M s}^{-1}$
1	$0.01$	$0.01$	$6.930\times10^{-6}$
2	$0.02$	$0.01$	$1.386\times10^{-5}$
3	$0.02$	$0.02$	$1.386\times10^{-5}$

\text{A}

and

\text{B}

are

0.5\,\text{M}

and

1\,\text{M}

, respectively, at

300\,\text{K}

. Find the reaction rate after

50

minutes. (a)
