The first step in HNO₃ production is the catalyzed oxidation of NH₃. Without a catalyst, a different reaction predominates:4NH₃(g) + 3O₂(g) ⇄ 2N₂(g) + 6H₂O(g)When 0.0150 mol of NH₃(g) and 0.0150 mol of O₂(g) are placedin a 1.00-L container at a certain temperature, the N₂ concentrationat equilibrium is 1.96x10⁻³M.
