Answer:
3 mol H2 / 1 mol NH3
Explanation:
Mole ratio depicts or shows the relationship between the number of moles of two substances in a chemical reaction. The following chemical equation is given:
N2 + 3H2 → 2NH3
According to the above chemical equation;
- 1 mole of N2 reacts
- 3 moles of H2 reacts
- 2 moles of NH3 is produced
Hence, this means that according to the options provided in this question, the incorrect one is 3 mol H2 / 1 mol NH3 because 2 moles rather than 1 mol of NH3 is involved.
