Complete Question

Answer:

The pressure is $[O_2] = 4.8 *10^{-5} \ atm$

Explanation:

From the question we are told that

The pressure of $SO_3$ is $[SO_3 ] = 0.63 \ atm$

The pressure of $SO_2$ is $[SO_ 2] = 0.30 \ atm$

The equilibrium constant is $K_p = 1.2 *10^{-5}$

The reaction is

$2SO_3 _{(g)}$ ⇔ $2SO_2_{(g)} + O_2 _{(g)}$

Generally the equilibrium constant is mathematically represented as

$K_p = \frac{(SO_2)^2 * (O_2)}{(SO_3)^2}$

=> $[O_2] = \frac{k_p * [SO_3] ^2 }{[SO_2]^2}$

substituting values

$[O_2] = \frac{1.2 *10^{-5} * 0.60 ^2 }{0.30^2}$

$[O_2] = 4.8 *10^{-5} \ atm$
