\begin{array}{c|c|c} \hline Interval & Conc.change & Rate \ \hline 0-17 \mathrm{~min} & 0.069-0.052=0.017 \mathrm{M} & \frac{0.017}{17}=0.001 \ \hline 17-34 \mathrm{~min} & 0.052-0.035=0.017 \mathrm{M} & \frac{0.017}{17}=0.001 \ \hline 34-51 \mathrm{~min} & 0.035-0.018=0.017 \mathrm{M} & \frac{0.017}{17}=0.001 \ \hline \end{array} ∵ Rate remains constant. So, it is independent of concentration, the reaction is of zero order. According to rate law Rate = K ( conc. ) 0 = 0.001 M / min
