One mole of PCl ₅( ~g ) was heated in a 1 ~L closed flask at 500 ~K . At equilibrium, 0.1 mole of Cl ₂( ~g ) was formed. What is its K _ p (in atm)? (Given R =0.082 ~L ~atm ~mol ⁻¹ ~K ⁻¹ )

Options

  1. A2.7 10⁻⁴
  2. B0.455
  3. C0.0111
  4. D90.0

Correct answer

B. 0.455

Step-by-step solution

aligned & K _ c = x ^2 1- x = (0.1)^2 0.9 =0.011 & Thus, K _ p =(0.011)(0.082 500)^ (2-1) & =0.451 . aligned
