Consider the equilibrium 2 NOCl(g) ⇄ CL₂ (g) + 2 NO(g).When 2.000 atm NOCl is placed in an empty tank at 500.0 K and allowed to come to equilibrium, the equilibrium partial pressure of Cl₂ is 0.226 atm.Calculate K_p.

Question

Quizplus · Accepted Answer

The equilibrium expression for the reaction is Kp = (P_NO^2 * P_Cl2) / (P_NOCl^2). At equilibrium, P_Cl2 = 0.226 atm, P_NO = 2 * 0.226 atm = 0.452 atm, and P_NOCl = 2.000 atm - 0.452 atm = 1.548 atm. Plug these values into the expression to find Kp = (0.452^2 * 0.226) / (1.548^2) = 0.0193.
