Answer 1

Answer #1

PCl5 -----> PCl3 + Cl2 , Kp = 0.0121

0.123 0 0 (at t=0)

0.123-x x x (at equilibrium)

Kp = P(PCl3) * P(Cl2) / P(PCl5)

0.0121 = x * x / (0.123-x)

0.0014883 - 0.0121x = x^2

x^2 + 0.0121x - 0.0014883 = 0

After solving above quadratic equation;

x = 0.0330

Hence,

Pressure of PCl3 at equilibrium = x = 0.033 atm
