The nitrogen atom is getting reduced.

Explanation:

Oxidation reaction is defined as the reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

The given chemical equation follows:

On reactant side:

Oxidation state of iron atom = +3

Oxidation state of nitrogen atom = +5

Oxidation state of sulfur atom = -2

On product side:

Oxidation state of iron atom = +3

Oxidation state of sulfur atom = 0

Oxidation state of nitrogen atom in = +4

Oxidation state of nitrogen atom in = +5

As, the oxidation state of nitrogen atom in is decreasing from +5 to +4. So, it is getting reduced.

And, oxidation state of sulfur atom is increasing from -2 to 0. So, it is getting oxidized.

Hence, the nitrogen atom is getting reduced.
