Nitrogen and oxygen react to produce nitric oxide according to the following equation: N2(g) + O2 (g) ? 2 NO (g) The equilibrium constant for this reaction is 1.70 x 10^-3. Suppose that 0.860 mol N2 and 0.580 mol O2 are mixed in a 4.00-L reaction vessel. What will be the concentrations of N2, O2, and NO when equilibrium is established?
