SO2(g) + O2(g) <−> SO3(g)
If the concentration of SO2(g) is increased, the equilibrium of the reaction will ___________.
SO2(g) + O2(g) <−> SO3(g)
If the equilibrium shifts to the right, the concentration of O2(g) will ___________.
N2O4(g) ↔ 2 NO2(g)
What is the concentration equilibrium constant expression?
Keq = [NO2]2/[N2O4]
Keq = [N2O4]/[NO2]2
Keq = [N2O4]2/[NO2]
Keq = [NO2]/[N2O4]2
CO2(g) + H2(g) ↔ CO(g) + H2O(l)
Fe3O4(s) + 4H2(g) <--> 3Fe(s) + 4H2O(g)

What is the Keq expression for the following reaction?
2 NO(g) + O2(g) ⇌2 NO2(g)
Keq = [NO2]2 / [NO]2[O2]
Keq = [NO]2[O2] / [NO2]2
Keq = [NO]2[O2][NO2]2
Keq = 2[NO][O2] / 2[NO2]
