Which of the following is redox reaction ?

A

`H_2SO_4` with NaOH

B

In atmosphere, `O_3` from `O_2` by lightning

C

Evaporation of `H_2O`

D

Nitrogen oxides form nitrogen and oxygen by lightning

Text Solution

Verified by Experts

The correct Answer is:
D
`overset(0)(2N_2)+overset(0)O_2rarroverset(+2)(2N)overset(-2)O`
Here O.N. of N increases from 0 in `N_2` to +2 in NO, and that of decreased from 0 in `O_2` to -2 in O, therefore, it is a redox reaction.
