Question

Q.6 Calculate the volume of H, required to prepare 20 litre of
NH3, according to given reaction.
N2 + 3H2 → 2NH2

Answer 1

Answer: 30 L

Explanation:  Acc. to reaction

                     3 moles of H2 give  2 moles of NH2

                 

                      it means  3 x22.4 L   H2 gives  2 x22.4 L  NH2

                       then 1 L NH2  gives   3 x 22.4 /2 x 22.4 L  of H2

                      or  20L NH2 gives    3 x20 /2 L  =30L H2
