For the reaction \[{{H}_{2}}(g)+B{{r}_{2}}(g)\to 2HBr(g)\], the experimental data suggest, rate \[=K[{{H}_{2}}]{{[B{{r}_{2}}]}^{1/2}}\]. The molecularity and order of the reaction are respectively [CPMT 1988; MP PET 1993]

A)                 \[2,\,\frac{3}{2}\]            

B)                 \[\frac{3}{2},\,\frac{3}{2}\]

C)                 1, 1
