Likewise, in thermochemistry, one has always stuck to the thermal effect, that is, to energy differences, until Wilhelm Ostwald in particular emphatically showed that many detailed considerations could be significantly abbreviated if one dealt with energy itself instead of with calorimetric numbers.
For his work in thermochemistry he received the Nobel Prize in
Great lessons there on thermochemistry, especially what an exothermic reaction is
Nernst of Berlin received this award for work in thermochemistry, despite a 16-year opposition to this recognition from Arrhenius
I now blog at battleoftheants.blogspot.com thermochemistry
Sabatier's earliest researches concerned the thermochemistry of sulphur and metallic sulphates, the subject for his thesis leading to his doctorate, and, in Toulouse, he continued his physico-chemical investigations to sulphides, chlorides, chromates and copper compounds.
Then came the heyday of thermochemistry, when it was believed that the explanation of the transformation of chemical energy during chemical reactions lay in the heat phenomena occurring during chemical processes.
Berthelot states, as one of the fundamental principles of thermochemistry, "that the quantity of heat evolved is the measure of the sum of the chemical and physical work accomplished in the reaction"; and such a law will no doubt account for the phenomena above noted.
Virtual Chemistry Laboratory allows students to design and perform diverse experiments in acid-base chemistry, thermochemistry, solubility, and redox chemistry.
One of these questions concerns itself with fuels and thermochemistry, the other is usually based on reaction type and mechanism.
