The most stable oxides of nitrogen will be :

Options

A. `2NO_(2)(g)hArrN_(2)(g)+2O_(2)(g), K=6.7xx10^(16)"mol l"^(-1)`
B. `2NO(g)hArrN_(2)(g)+O_(2)(g), K=2.2xx10^(30)"mol l"^(-1)`
C. `2N_(2)O_(5)(g)hArr2N_(2)(g)+5O_(2)(g), K=1.2xx10^(34)"mol l"^(-1)`
D. `2N_(2)O(g)hArr2N_(2)(g)+O_(2)(g), K=3.5xx10^(33)"mol l"^(-1)`

Answer

A

Explanation

Smaller the rate constant, higher will be the activation energy . So the compound will be more stable .
