Consider the following statements I NO is formed from N_(2) and O_(2) when lighting occurs at high altitude. II NO is formed when N_(2) is oxidized by O_(3) (III) NO is oxidized to NO_(2) by O_(2) or by O_(3) in the stratosphere. (IV) N_(2)O is formed by the reaction of N_(2) with O_(3) or with atomic oxygen in the upper atmosphere and also by microbiological process. Select the correct statements

Consider the following statements I NO is formed from N_(2) and O_(2)

1.	Consider the following statements I NO is formed from N_(2) and O_(2) when lighting occurs at high altitude. II NO is formed when N_(2) is oxidized by O_(3) (III) NO is oxidized to NO_(2) by O_(2) or by O_(3) in the stratosphere. (IV) N_(2)O is formed by the reaction of N_(2) with O_(3) or with atomic oxygen in the upper atmosphere and also by microbiological process. Select the correct statements
Answer» I,III and IV I,II and IV II,III and IV I,II and III Solution :`NO` is not FORMED by oxidation of `N_(2)` by `O_(3)` `N_(2)+O_(2) rarr 2NO` When lightning OCCURS THUS (I) is correct. `NO+O_(3) rarr NO_(2)+O_(2)` in the stratosphere thus (III) is correct. `N_(2)+O_(3) rarr N_(2)O+O_(2)` `N_(2)+Orarr N_(2)O` Thus, (IV) is correct.
