The nitrogen gas can be fixed spontaneously By:

Explanation

In industrial fixation, nitrogen gas (N2) is converted into a usable form, such as ammonia (NH3), through a process called the Haber-Bosch process. This process involves combining nitrogen gas and hydrogen gas under high pressure and temperature in the presence of a catalyst. The resulting ammonia can then be used as a fertilizer or in the production of various chemical compounds. Industrial fixation plays a crucial role in providing the nitrogen needed for agriculture and other industries.
