  ARRHENIUS, Svante August
Arrhenius pointed out that, although the molecules of those chemical compounds that have solutions able to conduct an electric current are broken down in solution into electrically charged particles called ions, such dissociation is practically complete even when no passage of electric current occurs.
In 1889 Arrhenius also observed that the speed of chemical reactions increases markedly when the temperature is increased, at a rate proportional to the concentration of the activated molecules.
Arrhenius became professor of chemistry at the University of Stockholm in 1895 and director of the Nobel Institute of Physical Chemistry in 1905.

  Svante Arrhenius
Svante August Arrhenius (February 19, 1859-October 2, 1927) was a Swedish scientist working on the border between physics and chemistry.
Arrhenius was born at Vik (also spelled Wik or Wijk), Kalmar district, near Uppsala, Sweden, the son of Svante Gustav and Carolina Thunberg Arrhenius.
Arrhenius declined, however, as he preferred to stay in Sweden for a while (his father was very ill and would die in 1885) and had gotten an appointment at Uppsala.

SVANTE AUGUST ARRHENIUS (1859-), Swedish physicist and chemist, was born on the 19th of February 1859, at Schloss Wijk, near Upsala.
Arrhenius is specially associated with the development of the theory of electrolytic dissociation, and his great paper on the subject, Recherches sur la conductibilite galvanique des electrolytes - (1) conductibilite galvanique des solutions aqueuses extremement diluees, (2) theorie chimique des electrolytes, was presented to the Stockholm Academy of Sciences in 1883.
He was subsequently continuously engaged in extending the applications of the doctrine of electrolytic conduction in relation not only to the problems of chemical action but also, on the supposition that in certain conditions the air conducts electrolytically, to the phenomena of atmospheric electricity.

Svante August Arrhenius and Walther Nernst were two of the founders of the new physical chemistry.
Arrhenius’ life can be conveniently divided into three major portions, corresponding to the three major sections in Crawford’s biography: his education and work in solution theory (for which he is most famous), his study of cosmic physics, and his work in immunochemistry (Arrhenius invented the term).
In the theoretical part, Arrhenius explained the results of the first, by introducing the concept of active (conducting) and inactive (non-conducting) molecules, and the activity coefficient, which elaborated on the Clausius-Williamson hypothesis that assumed the molecules were dissociated before the current was applied, and that all ions had the same amount of electricity.

A hundred years ago, Swedish scientist Svante Arrhenius asked the important question “Is the mean temperature of the ground in any way influenced by the presence of the heat-absorbing gases in the atmosphere?” He went on to become the first person to investigate the effect that doubling atmospheric carbon dioxide would have on global climate.
In this book Arrhenius first describes the “hot-house theory ”of the atmosphere, stating that the Earth's temperature is about 30 degrees warmer than it would be due to the“ heat-protection action of gases contained in the atmosphere,”a theory based on ideas developed by Fourier, Pouillet, and (especially) Tyndall.
It is important to note that Arrhenius was not very concerned with rising carbon dioxide levels at the time, but rather was attempting to find an explanation for high latitude temperature changes that could be attributed to the onset of the ice ages and interglacial periods.
