The value of Kp for the system = 0.0128 atm
Explanation:
Let, the gaseous substance is SO₂Cl₂
SO₂Cl₂ ⇄ SO₂ + Cl₂
Initially x 0 0
At equilibrium (x - 14.5%x) 14.5%x 14.5%x
= 85.5 % x
Total moles of gases at equilibrium
= 85.5 % x + 14.5%x + 14.5%x
= 114.5 % x
Partial pressure of SO₂ (
) = ![\frac{14.5x}{114.5x} X0.67= 0.08](/tpl/images/0587/0666/6c008.png)
Partial pressure of Cl₂![(Pcl_{2}) =\frac{14.5x}{114.5x} X0.67 = 0.08](/tpl/images/0587/0666/76cb5.png)
Partial pressure of SO₂Cl₂![(Pso_{2}cl_{2} )=\frac{85.5x}{114.5x} X0.67= 0.5](/tpl/images/0587/0666/7cf96.png)
