The industrial production of ammonia involves the Haber process.
One of the steps in this process is the reversible reaction between nitrogen and hydrogen gases:
N2(g)+3H2(g)⇌2NH3(g) \text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g}) N2(g)+3H2(g)⇌2NH3(g)What volume of ammonia (NH3\text{NH}_3NH3), in dm3\text{dm}^3dm3, is produced by the complete reaction of 600 dm3 of hydrogen gas with excess nitrogen? (All volumes of gases are measured under the same conditions of temperature and pressure.)
