In the lower atmosphere, ozone is formed by the reaction between

A

`O_(2)` and `CFCs`

B

`NO_(2)` and `O_(2)`

C

`O_(2)` and `NO`

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
B
`NO_(2)+hv rarr NO+O`
`O_(2)+O+M rarr O_(3)+M`
where `M`, represents a third body (a molecule or a particle) needed to absorb the excess energy of the reaction, without which there would just be an exchange of oxygen atoms within the oxygen molecule. Reaction with `NO` keeps the concentration of `O_(3)` in balance called steady state (0.025ppm)`.
