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

EMI1.2
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.
In order to obtain at least measurable amounts of ammonia when studying the ammonia equilibrium, Nernst has the reaction under pressure
