A closed vessel impermeable to heat contains ozone (O${}_3$) at $t_1=527^{\circ }$C. After some time the ozone is completely converted into oxygen (O${}_2$). Find the increase of the pressure in the vessel (as $\frac{P_2}{P_1}$) if $q=34$ kcal has to be spent to form one g-mole of ozone from oxygen. $M_1=48$, $M_2=32$, $C_v$ of oxygen = $5$ cal $de{g}^{-1}$ $mol{e}^{-1}$.
