Which of the following is redox reaction ?

A

`H_(2)SO_(4)` with `NaOH`

B

In atmosphere, `O_(3)` from `O_(2)` by lightning

C

Evaporation of `H_(2)O`

D

Nitrogen oxides from nitrogen and oxygen by lightning

Text Solution

Verified by Experts

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