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
