Which oxide of nitrogen is the most stabel?

Options

A. `2NO_(2(g))hArrN_(2(g))+2O_(2(g))` , `K=6.7xx10^(16) mol litre^(-1)`
B. `2NO_((g))hArrN_(2(g))+O_(2(g))` , `K=2.2xx10^(30) mol litre^(-1)`
C. `2N_(2)O_(5(g))hArr2N_(2(g))+5O_(2(g))` , `K=1.2xx10^(34) mol^(5) litre^(-5)`
D. `2N_(2)O_((g))hArr2N_(2(g))+O_(2(g))` , `K=3.5xx10^(33) mol litre^(-1)`

Explanation

Greater is the value of `K`, more will be the tendency to show forward reaction.
