Phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reaction:
PCl₃(g) + Cl₂(g) ⇌ PCl₅(g)
An equilibrium mixture at 450 K contains
P_PCl₃ = 0.124 atm,
P_Cl₂ = 0.157 atm,and
P_PC_l₅ = 1.30 atm.What is the value of K_p at this temperature?

Quizplus · Accepted Answer

The equilibrium constant, Kp, is given by the expression:Kp = (PCl5) / (PCl3) * (PCl2)Substituting the given partial pressures into the expression, we get:Kp = (1.30 atm) / (0.124 atm) * (0.157 atm) = 66.7Therefore, the value of Kp at 450 K is 66.7.
