From previous experiments, you have the following information.

N2(g)+O2(g)<--->2NO(g) Kc=2.3*10^-19
2NO(g)+O2(g)<--->2NO2(g) Kc=3*10^6

using that information, how many moles of NO2(g) will be made if you started with 1 moles of N2(g) and 2 moles of O2 (g)?

N2(g)+2O2(g)<--->2NO2(g)

  • Chem -

    The reaction equation is just the sum of equation 1 and equation 2. Therefore, Kc for the reaction equation is k1*k2 = 6.9E-13
    ............N2 + 2O2 ==> 2NO2
    I...........1.....2.......0
    C..........-x....-2x......+2x
    E..........1-x..2-2x.......2x
    Substitute into Kc expression for the new reaction and solve. You want to find 2x = mols NO2
