On Enantiotropy and Monotropy. Ii

Abstract

1. The affinity of transition and the heat of transition from diamond to graphite and from white phosphorus to red phosphorus have been evaluated on the basis of the Nernst’s theorem and it has been made clear that they are monotropic under the atmospheric pressure. The former case will probably be enatiotropic under high pressure, whereas the latter case will remain monotropic even under high pressure. 2. An approximation formula for the estimation of the affinity of transition has been derived and by means of which the dimorphisms in ethyl ether, iodine monochloride, benzophenone, phthalide, bromonitrobenzene, acetamide, monochloracetic acid, nitro-p-toluide and erythrite have been estimated to be monotropic.
