Question

If in the reaction N2+O2=2NO , the production of the reaction of NO is 40%at equilibrium. Then Kc for the is

Answer 1

If nN2=nO2=0.5 => nNO=40%x1=0.4

N2 + O2 =2NO

0.5      0.5

0.2       0.2   0.4

0.3        0.3    0.4

Kc=[NO]^2/[N2][O2]=0.4²/0.3x0.3=1.8

Answer 2

Explanation:

If nN2=nO2=0.5 => nNO=40%x1=0.4

N2 + O2 =2NO

0.5 0.5

0.2 0.2 0.4

0.3 0.3 0.4

Kc=[NO]^2/[N2][O2]=0.4²/0.3x0.3=1.8
