Two solids dissociate as follows –

The total pressure when both the solids dissociated simultaneously is -

Accepted Answer

K_p₁ = P₁(P₁ + P₂)

K_p₂ = P₂(P₁ + P₂)

\therefore

K_p₁ + K_p₂ = (P₁ + P₂)²

\Rightarrow

x + y = (P₁ + P₂)²

\Rightarrow

(P₁ + P₂) =

\sqrt {x + y}

.....(1)

Now total pressure

P_T = P_C + P_B + P_E

= (P₁ + P₂) + P₁ + P₂

= 2(P₁ + P₂)

=

2\sqrt {x + y}

[From equation (1)]
