Die Reaktion war also nur von   theoretischem   Interesse, eine technische Verwendung derselben aber völlig ausgeschlossen.

   Um bei dem Studium des Ammoniak-Gleichgewichtes wenigstens   messbare Mengen Ammoniak   zu erhalten, hat Nernst die Reaktion unter Drucken

 The ammonia yields obtained with the best-performing known catalysts were so slight that even the analytical determination made them difficult. The reaction was therefore only of theoretical interest, but its technical use was completely excluded.
