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
CO (g) + 3H2 (g) <----> CH4 (g) + 3H2O (g) At equilibrium [CO] = 4.0 M. [H2] = 2.8 M. [CH4] = .75 M, and [H2O] = .12M. Find the Keq constant.
Keq =1.65 x 104
Keq = 6.5 x 10-6
Keq = 1.48 x 10-5
Keq = 3.2 x 105

For the reaction SO2(g) + NO2(g) <-> SO3(g) + NO(g), the equilibrium constant is 18.0 at 1,200ºC. If 0.05 M of SO2 and 0.10 M NO2 are placed in a container, what concentration of SO3 will be present at equilibrium?
0.11 M
0.95 M
0.30M

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]
