$A _{( g )} \rightarrow 2 B _{( g )}+ C _{( g )}$
$P _{0}$ be initial pressure of $A$ and $P _{ t }$ the total pressure at time $'t'$. Integrated rate equation is :
${C_6}{H_6}\left( \ell \right) + \frac{{15}}{2}{O_2} \to 6C{O_2}\left( g \right) + 3{H_2}O\left( \ell \right)\,\,\,\,\Delta H = - 3271\,kJ$
