Consider the following reactins involving some atmospheric pollutants.
`NO + O_(3) to NO_(2) + O_(2) overset(hv) to NO + O_(3)`
`4NO _(2) + O _(2) + 2H_(2)O to 4HNO_(3)`
`3CH_(4) + 2O_(3) to 3H_(2) C=O+ 3H_(2)O`
Based on the above, the formation of formaldehyde from methane in the atmosphere will be controlled by,

Options

A. Only `O _(3)`
B. `O_(3) and NO _(2)`
C. `O_(3),NO and NO _(2)`
D. `NO and NO _(2)`

Answer

C

Explanation

Following reactions involve some atmospheric pullutants.
`N + O _(3) to NO _(2) + O_(2) overset(hv) to NO + O _(3)`
`NO _(2) + O _(2) + 2H_(2)O to 4HNO_(3)`
`3CH_(4) + 2O_(3) to 3H_(2) C =O+ 3H_(2) O`
The formation of formaldehyde from methane `(CH_(4))` in the atmosphere will be controlled by `O _(3) and NO _(2)`
