Question

The equilibrium constant (KC) for the reaction N2(g) + O2(g) → 2NO(g) at temperature T is 4 × 10-4. The value of KC for the reaction. NO(g)→ 1/2 N2 (g) + 1/2 O2(g) at the sametemperature is :-

Options

A.50.0
B.0.02
C.2.5 × 102 
D.4 × 10-4 

Solution

N2 + O2 → 2NO     KC = 4 × 10-4
2NO → N2 + O2   
NO →
