Dinitrogen and dioxygen are main constituents of air but these do not react with each other to form oxide of nitrogen because `"…….."`.

A

the reaction is endothemic and requires very high temperature

B

the reaction can be initiated only in presence of a catalyst

C

oxides of nitrogen are unstable

D

`N_(2)` and `O_(2)` are unreactive

Text Solution

Verified by Experts

The correct Answer is:
A
Major component of atmosphere are dinitrogen,dioxygen and water vapour
`N_(2) = 78.08%, O_(2) = 20.95%`
Both do not react with each other as nitrogen is an inactive gas. The triple bond in `N_(2)` is very stable and its dissociation energy is very high. Both react with each othr at very high temperature.
`N_(2)(g) + O_(2)(g) overset(3000^(@)C)rarr 2NO(g)`
