The reaction of nitrogen gas and oxygen gas to form nitrogen monoxide gas is shown below. If the measured concentrations of all three chemicals at some point in time are: [N2] = 0.80 M

[O2] = 0.050 M
[NO] = 0.10 M
Which statement is TRUE about the reaction at this point in time? N2(g) + O2(g) ⇄ 2 NO(g) K = 0.10

1. The reaction is at equilibrium.
2. The reverse reaction is occurring at a faster rate than the forward reaction.
3. The forward reaction is occurring at a faster rate than the reverse reaction.
4. This set of concentration values is impossible because the concentrations of N2 and O2 must be the same.
