Which oxide of nitrogen is the most stable:

Options

A. `2NO_2(g) ⇌ N_2(g) + 2O_2(g)
K = 6.7 xx 10 ^(16) mol litre^(-1)`
B. `2NO(g) ⇌ N_2(g) + O_2(g) ,
K = 2.2 xx 10^(30) mol litre^(-1)
C. `2N_2O_5(g) ⇌ 2N_2(g) + 5O_2(g) ,
K = 3.5 xx 10 ^(33) mol^(-5) litre^(-5)`
D. `2 N_2O(g) ⇌ 2N_2(g) + O_2(g) , K = 3.5 xx 10^(33) mol litre^(-1)`

Answer

A
