320507 For the reaction \(\mathrm{aA} \rightarrow \mathrm{xP}\) when \({\text{[A] = 2}}{\text{.2 mM}}\) the rate was found to be \({\text{2}}{\text{.4 m M}}{{\text{s}}^{{\text{ - 1}}}}\). On reducing the concentration of A to half, the rate changes to \({\text{0}}{\text{.6 mM}}{{\text{s}}^{{\text{ - 1}}}}\). The order of reaction with respect to \(\mathrm{A}\) is

1 \({\text{1}}{\text{.5}}\)
2 \({\text{2}}{\text{.0}}\)
3 \({\text{2}}{\text{.5}}\)
