The reaction below was studied at a high temperature.At equilibrium,the partial pressures of the gases are as follows: PCl₅ = 1.4 × 10−⁴ atm,PCl₃ = 2.4 × 10−² atm,Cl₂ = 3.0 × 10−¹ atm.What is the value of K for the reaction? PCl₅(g) ⇌ PCl₃(g)+ Cl₂(g)

Question

Quizplus · Accepted Answer

The equilibrium constant K is calculated using the expression K = (PCl3)(Cl2)/(PCl5). Substituting the given pressures, K = (2.4 × 10−2)(3.0 × 10−1)/(1.4 × 10−4) = 51.
