${\left( {C{H_3}} \right)_2}CHN = NCH{\left( {C{H_3}} \right)_2}\left( g \right)\xrightarrow[{{{\text{N}}_2}{\text{(g) + }}{{\text{C}}_6}{{\text{H}}_{14}}{\text{(g)}}}]{{250 - 290{}\,^oC}}$
It is found to be a first order reaction. If initial pressure is $P_o$ and pressure of the mixture at time $t$ is $(P_t)$ then rate constant $K$ would be
$(CH_3)_2CHCH_2N(CH_2CH_3)_2 \xrightarrow{C{{H}_{3}}I}\xrightarrow[{{H}_{2}}O]{A{{g}_{2}}O}\xrightarrow{heat}$ products
