The following data pertains to reaction between \( A \) and \( B \) :
\( \begin{array}{llll}\text { S. No. } & {[A] \mathrm{mol} \mathrm{L}^{-1}} & {[B] \mathrm{mol} \mathrm{L}^{-1}} & \text { Rate }\left(\mathrm{mol} \mathrm{L}^{-1} \text { time }^{-1}\right) \\ 1 & 1.0 \times 10^{-2} & 2.0 \times 10^{-2} & 2.0 \times 10^{-4} \\ 2 & 2.0 \times 10^{-2} & 2.0 \times 10^{-2} & 4.0 \times 10^{-4} \\ 3 & 2.0 \times 10^{-2} & 4.0 \times 10^{-2} & 8.0 \times 10^{-4}\end{array} \)
Which of the following inference(s) can be drawn from the above data?
(i) Rate constant of the reaction is \( 1.0 \times 10^{-4} \).
(ii) Rate law of the reaction is : rate \( =k[A][B] \)
(iii) Rate of reaction increases four times on doubling the concentration of both the reactants.
Select the correct answer using the codes given below :
(a) (i), (ii) and (iii)
(b) (i) and (ii)
(c) (ii) and (iii)
(d) (iii) only
