Initial rate of |
| $0.1\,M$ | $0.1\,M$ | $1.2 \times 10^{-3}$ |
| $0.1\,M$ | $0.2\,M$ | $1.2 \times 10^{-3}$ |
| $0.2\,M$ | $0.1\,M$ | $2.4 \times 10^{-3}$ |
For the reaction the rate of formation of $C$ will be
$C{{H}_{3}}-C{{H}_{2}}-COOH\xrightarrow{PC{{l}_{3}}}I\xrightarrow{{{C}_{6}}{{H}_{6}}/AlC{{l}_{3}}}II\xrightarrow[\text{base/heat}]{N{{H}_{2}}-N{{H}_{2}}}III$
