frozen [14]

Complete Question

The complete question is shown on the first uploaded image

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
