How many liters of NH3 can be produced from the reaction of 6.57L of N2 with an excess of H2? N2 + H2–-> NH3

13.14L

Explanation:

The reaction expression is given as:

      N₂   +   3H₂    →   2NH₃

The given reaction is not balanced and we have balanced it as shown above in the reaction.

       N₂   +   3H₂    →   2NH₃

Based on the Avogadro's law, equal volume of all gases contains the same number of molecules at the same temperature and pressure.

                      1 L of   N₂  will produce  2L of NH₃

So                  6.57L of N₂ will produce 2 x 6.57  = 13.14L of NH₃
