Problem: The Haber process is the principal industrial route for converting nitrogen into ammonia:N2 (g) + 3H2 (g)  →  2NH3 (g).What is being oxidized, and what is being reduced?

FREE Expert Solution

To determine which element is reduced or oxidized, we must identify the changes in their oxidation states

Compare the oxidation number of the element on the reactant side and on the product side.
