Answer» the reaction is endothermic and requires very high temperature the reaction can be initiated only in presence of a catalyst. oxides of nitrogen are UNSTABLE. `N_2 and O_2` are UNREACTIVE. Solution : the reaction is endothermic and requires very high temperature. Major compounds of atmosphere are DINITROGEN, DIOXYGEN and water vapour. N2 = 78.08 %, 0, = 20.95%. Both dinitrogen and dioxygen do not react with each other because nitrogen is an inactive gas. The triple bond in N, is very stable and its dissociation energy is very high. N, and 02 reach with each other at very high temperature. `N_(2(g)) + O_(2(g)) overset(3000^@C)to 2NO_((g))`
