Plants convert nitrogen into ammonia. This biological nitrogen fixation is effected by enzymes called nitrogenases. The enzymes assist in the transfer of electrons. The unbalanced reaction equation is
N₂(g) + H⁺(aq) + e^- $\rarr$ H₂(g) + NH₃(aq)
What is the change in the oxidation number of nitrogen in this reaction?

Question

Plants convert nitrogen into ammonia. This biological nitrogen fixation is effected by enzymes called nitrogenases. The enzymes assist in the transfer of electrons. The unbalanced reaction equation is

\rarr

H₂(g) + NH₃(aq)
What is the change in the oxidation number of nitrogen in this reaction?

Quizplus · Accepted Answer

In this reaction, the nitrogen in N₂(g) has an oxidation number of 0. In the product NH₃(aq), the oxidation number of nitrogen is -3. Therefore, the change in oxidation number of nitrogen is -3 - 0 = -3. Therefore, the answer is B, -3.
