164230 For the reaction, \(2 A+B \rightarrow\) Products the following initial rates were obtained at various initial concentrations :

[A]{\([B]\)}Rate \(\left(\mathrm{mol} \mathrm{l}^{-1} \mathrm{sec}^{-1}\right)\)
\(0.1 \mathrm{M}\)\(0.2 \mathrm{M}\)0.46
\(0.2 \mathrm{M}\)\(0.2 \mathrm{M}\)1.84
\(0.2 \mathrm{M}\)\(0.1 \mathrm{M}\)0.92

The rate law for the reaction is :

1 Rate \(=k[A]^2[B]^0\)
2 Rate \(=k[A][B]\)
3 Rate \(=k[A]^2[B]\)
4 Rate \(=k[A][B]^2\)
