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