I Review | Constants | Periodic Table The industrial production of nitric acid (HNO3) is a multistep process. The first step is the oxidation of ammonia (NH3) over a catalyst with excess oxygen (O2) to produce nitrogen monoxide (NO) gas as shown by the unbalanced equation given here: Submit Previous Answers v Correct ?NH3(9)+?O2(9)–→?NO(g)+?H2O(g) Correct answer is shown. Your answer 443.34 L was either rounded differently or used a different number of significant figures than required for this part. You have calculated the theoretical volume of O2 needed to produce 18.0 mol of NO. However, in the industrial production of NO, oxygen is added in excess of this amount.
