Ammonia and all deuerium-containing forms of ammonia
, and
) are present.
Dihydrogen and all deutrated forms (
and
) are present.
All of these
Answer :
D
Solution :
Chemical equilibrium is dynamic in nature, i.e., both forward and reverse reactions are still going on but at equal rates. Scrambling of
and
atoms in the molecules results from a continuation of the forward and backward reactions in the mixture. If the reactions has simply stopped when they reached equilibrium, then there would have been no mixing of isotopes in this way. Thus, the use of isotope (deuterium) in the formation of ammonia clearly indicates that chemical equilibrium is dynamic in nature.
