Answer to Question #150479 in General Chemistry for kate

Question

Consider the reaction below. At 305 K, the Keq value is 14.15. Initially, 0.81 mol of PCl3(g) and 1.37 mol Cl2(g) are placed into a 1.00 L container and allowed to reach equilibrium. What are the equilibrium concentrations of all these substances?



PCl3(g) + Cl2(g) PCl5(g)

Answer 1

c(PCl₃) = 0.81 mol/L

c(Cl₂) = 1.37 mol/L

c(PCl₅) = 0.08 mol/L
