Equilibrium #1

The equilibrium constant $K_{p}$ of the reaction $2\text{SO}_{2}(g)\quad +\quad \text{O}_{2}(g) \quad \iff \quad 2\text{SO}_{3}(g)$ is 900 atm at 800 K . A mixture containing $\text{SO}_{3}$ and $\text{O}_{2}$ having initial pressure of 1 and 2 atm respectively is heated at constant volume to equilibrium. Calculate the sum of the partial pressures of all gases at 800 K.

Unit of partial pressure is atm .

$\iff$ denotes reaction in forward as well as backward direction.
