Which of the following terms would be included in an equilibrium constant expression?

Question

Select all that apply.

A. H₂O(g)

B. N₂(g)

C. NH₃(g)

D. H₂O(s)

E. H₂O(l)

F. NaCl(s)

Answer 1

For the equilibrium constant Kc expression, solids and liquids are omitted. For example, if you have the chemical equation

2 C6H6 (g) + 15O2 (g) <----> 12 CO2 (g) + 6 H2O (g)

All of these would be included in the Kc equation because they are not solids or liquids

In this case, Kc =

([CO2]^12 x [H2O]^6) / ([C6H6]^2 x [O2]^15)
