Q: In the reaction 3H2 + N2 → 2NH3, which element is reduced? (2022)
Solution:
N2 is reduced to NH3 as it gains electrons.
Steps: 6
Show Steps
Step 1: Identify the reactants and products in the reaction. The reactants are H2 and N2, and the product is NH3.
Step 2: Determine the oxidation states of each element in the reactants and products.
Step 3: In H2, hydrogen (H) has an oxidation state of 0. In N2, nitrogen (N) also has an oxidation state of 0.
Step 4: In NH3, hydrogen (H) has an oxidation state of +1, and nitrogen (N) has an oxidation state of -3.
Step 5: Compare the oxidation states before and after the reaction. Nitrogen goes from 0 in N2 to -3 in NH3, which means it gains electrons.
Step 6: Since gaining electrons indicates reduction, we conclude that nitrogen (N2) is reduced to ammonia (NH3).
