Question

XY2 dissociates as : XY (g) XY(g) Y(g) Initial pressure of XY2 is 600 mm Hg. The total pressure at equilibrium is 800 mm Hg. Assuming volume of system to remain constant, the value of Kp is

Answer: B

💡 Solution & Explanation

2 XY XY Y Initially 600 0 0 Equilibrium 600 p p p Total pressure 600 p p p 800 p p = 800-600 = 200 200×200 40000 K = = = 100 400 400
