The experimental data for the reaction \[2A+{{B}_{2}}\to 2AB\] is [CBSE PMT 1997]

Exp.	\[{{[A]}_{0}}\]	\[{{[B]}_{0}}\]	Rate (mole \[{{s}^{-1}}\])
(1)	0.50	0.50	\[1.6\times {{10}^{-4}}\]
(2)	0.50	1.00	\[3.2\times {{10}^{-4}}\]
(3)	1.00	1.00	\[3.2\times {{10}^{4}}\]

                The rate equation for the above data is                

A)                 Rate \[=k\,[{{B}_{2}}]\]                

B)                 Rate \[=k\,{{[{{B}_{2}}]}^{2}}\]

C)                 Rate \[=k{{[A]}^{2}}\,{{[B]}^{2}}\]           

D)                 Rate \[=k\,{{[A]}^{2}}[B]\]
