Abstract

John Hughes Davies, born in Merthyr Tydfil, Wales, carried out expts. to study the effect of the silent discharge on the formation and decompn. of ammonia. He concluded that he had shown the decompn. of ammonia by the silent elec. discharge to essentially a reaction of the first order. The decompn. const., approx. a linear function of the current strength, has a temp. coeff. much smaller than those of chem. reactions in general. Approx. 3% of ammonia remains when equil. is reached. The same percentage is obtained in formation expts. with a stoichiometric mixt. of nitrogen and hydrogen. However, the percentage of ammonia formed is smaller in nonstoichiometric mixts. and the results do not fit the requirements of the law of mass action.
