Solution: Consider this reaction.P(s) + 6 Cl(g) ⇌ 4 PCl(g)What is the correct Kc expression for this reaction?  

Solution: Consider this reaction.P4 (s) + 6 Cl2 (g) ⇌ 4 PCl3 (g)What is the correct Kc expression for this reaction?  


Consider this reaction.

P(s) + 6 Cl(g) ⇌ 4 PCl(g)

What is the correct Kc expression for this reaction?




Kc is the equilibrium expression of the concentrations in the reaction. The general form of an equilibrium expression is:

Given reaction:

P4(s)  +  6 Cl2(g)  ⇌  4 PCl3(g)
