AIn atmosphere, [IMAGE] from [IMAGE] by lightningBEvaporation of [IMAGE]CNitrogen oxides form nitrogen and oxygen by lightning

Show answer and solution▾

[IMAGE] Here O.N. of N increases from O in [IMAGE] to +2 in
[IMAGE] and that of decreased from O in
[IMAGE] to -2 in O, therefore, it is a redox reaction.
