Dinitrogen and dioxygen. the main constituents of air do not react with each other in atmosphere to form oxides of nitrogen because
- (A) is unreactive in the condition of atmosphere.
- (B)Oxides of nitrogen are unstable.
- (C)Reaction between them can occur in the presence of a catalyst.
- (D)The reaction is endothermic and require very high temperature.✓ Correct
Answer: (D)
Solution
The reaction between nitrogen and oxygen is:
This reaction is endothermic and requires very high temperatures (1483-2000 K) to proceed. Under normal atmospheric conditions, the temperature is too low for this reaction to occur at any significant rate. The reaction becomes feasible only at very high temperatures, such as in lightning strikes or in internal combustion engines.
