For , initially 1 mole each of XY2 & Y are present in 10 lit flask at 500 mm. If the equilibrium pressure of XY is 150mm, KP is

Initial moles of XY2 = Initial moles of Y = 1initial pressure = 500 mmGiven equilibrium pressure of XY = 150 mmPressure of gas α no. of mole1 mole of XY2 gives 1 mole of XY___ mm of XY2 gives 150 mm ofDecrease in pressure of XY2 = 150 mm
