Chemistry - Stoichiometry Question with Solution | TestHub

Carbon mono oxide $(\mathrm{CO})$ and oxygen ${\mathrm{O}}_2$ react according to :

$2CO(g)+O_2(g)\to 2C{O}_2(g)$

Assuming that the reaction takes place and goes to completion, let $P$ be the partial pressure of O₂ after the valve is opened in the apparatus represented in the accompanying figure. Find the value of $1/P$ in atm⁻¹. Also, assume that the temperature is fixed at $300K$.
