K=6.7 xx 10^(16)" mol L"^(-1)`
B. `2N_(2)O_(5) (g) Leftrightarrow 2N_(2) (g)+5O_(2) (g), K=1.2 xx 10^(24)" mol"^(5) L^(-5)`
C. `2NO(g) Leftrightarrow N_(2) (g)+O_(2) (g), K=2.2 xx 10^(30)`
D. `2N_(2)O(g) Leftrightarrow 2N_(2)(g)+O_(2)(g), K=3.5 xx 10^(33)mol L^(-1)`

Answer

A

Explanation

The oxide which has more `K_(c)` value for this formation is more stable
