Text Solution

Verified by Experts

The correct Answer is:
A
Birkeland-Eyde process
Dinitrogen is prepared commerically from air by liquefaction and fractional distillation. When liquid air is allwed to distil, dinitrogen having lower `b.pt (77K)` distils over first leaving behind liquid oxygen `(bpt 90K)`. worldwide production of dinitrogen from liquid air is more than `50` million tons per year.
