<P> Final Answer : K_p = 100 MM HG

Steps:

1) We have,

Since, Volume is constant .

XY_2(g) \rightarrow XY(g) + Y(g) \\ \\ \\t=0 => 600. \rightarrow 0 \quad + 0 \\ \\ t=t_{eq. } => 600-x \rightarrow x.\quad + x

2) Then at Equilibrium

P_T = P_{XY_2}+ P_{XY} + P_Y \\ \\ => P_T = (600-x) + x + x \\ \\ => 800 = 600+ x \\ \\ => x = 200 mm \:Hg

3) Now,

K_p = \frac{x*x}{(600-x) } \\ \\ K_p = \frac{200*200}{400} = 100 mm\: Hg

Hence, Value of K_p = 100 \: mm Hg
