at a certain temperature, the following reaction has an equilibrium constant of Kp=401

At a certain temperature, the following reaction h

Answer 1

Answer #1

PCl₃ + Cl₂ -----> PCl₅

Intial Pressure 0 0 0.078 bar

Change P -x -x +x bar

Equli P -x -x 0.078 + x bar

Kp = (0.0780 + x) / x² = 401

401x² -x -0.078 = 0

x = 0.015249

So total pressure at equilibrium = 0.015249 (PCl₃) + 0.015249 (Cl₂) + [0.015249+0.078] (PCl₅)

total pressure at equilibrium = 0.1237 bar
