The first stage of the industrial manufacture of nitric acid (the Ostwald process) involves the catalytic oxidation of ammonia to form nitrogen monoxide and steam:
4NH3(g)+5O2(g)→4NO(g)+6H2O(g) 4\text{NH}_3(\text{g}) + 5\text{O}_2(\text{g}) \rightarrow 4\text{NO}(\text{g}) + 6\text{H}_2\text{O}(\text{g}) 4NH3(g)+5O2(g)→4NO(g)+6H2O(g)What is the total volume of gaseous products, in dm3\text{dm}^3dm3, formed by the complete reaction of 180 dm3 of ammonia gas with excess oxygen? (All gas volumes are measured under the same conditions of temperature and pressure.)
