Bronsted-Lowry acid?

N2 + 3H2 <--> 2NH3

Is this a bronsted-Lowry reaction (specifically does the NH3 act as an Bronsted-Lowry acid)??

In the chem/bio, are the answers ever "None of the Above" in the real DAT?

When the reverse reaction is occuring, ammonia has lost all its protons, thus making it a bronsted acid.

But a requirement of the Bronsted-Lowry Definition is the presence of a Conjugate Acid and A Conjugate Base. For this to happen, an even number of molecules must be present..
And also, isnt Bronsted-Lowry always in Water?

This is not an acid/base reaction. In order to be an acid/base reaction, you need both acid and base.

This reaction is just a synthesis reaction, more specifically, a redox reaction. You can see that oxidation number is changing for N and H.
