Solution

The correct option is B False
Nitrogen and Oxygen combine to form nitric oxide. This is an endothermic reaction. The energy required to break the strong triple bond in a nitrogen $(N_{2})$ molecule is higher than the energy released in the formation of nitric oxide $(N O)$ . So, this is an endothermic reaction.
$N_{2} + O_{2} \to 2 N O$
