Question
For the reaction N2(g) + O2(g) ⇋ 2NO (g), the equilibrium constant is K1. The equilibrium constant is K2 for the reaction 2NO (g) + O2(g) ⇋ 2NO2(g), What is K for the reaction NO2(g) ⇋ 
N2(g) + O2(g) ?
N2(g) + O2(g) ?Options
A.1/( 4 K1 K2 )
B.[1/( K1 K2)]1/2
C.1/( K1 K2 )
D.1/( 2 K1 K2 )
Solution
N2(g )+ O2(g) ⇋ 2NO (g); K1 ....(i)
2NO (g) + O2(g) ⇋ 2NO2(g); K2 ....(i)
N2(g) + O2(g) ⇋ 2NO2(g); K = K1 × K2
∴ For NO2(g) ⇋
N2(g) + O2(g); K = 
2NO (g) + O2(g) ⇋ 2NO2(g); K2 ....(i)
N2(g) + O2(g) ⇋ 2NO2(g); K = K1 × K2
∴ For NO2(g) ⇋
N2(g) + O2(g); K = Create a free account to view solution
