1. At 2273 K, Keq = 6.2 multiplied by 10-4 for the following reaction.

N2(g) + O2(g) equilibrium reaction arrow 2 NO(g)
If [N2] = 0.04700 mol/L and [O2] = 0.01200 mol/L, what is the concentration of NO at equilibrium?

please answer and explain this one as well.

2. CO(g) + 2 H2(g) <==> CH3OH(g)

Keq = 10.5 = (CH3OH)/(CO)(H2)^2
You know K, (CH3OH), and (CO). Substitute and solve for (H2)

3. For the N2 + O2 ==> 2NO problem, is 0.04700 M and 0.01200 M the concentrations at the beginning of the reaction and you want to find the equilibrum concns for NO OR are those concns those at equilibrium and you want to find the equilibrium concn of NO?
