Work

During chemical reactions, atoms and molecules regroup and form new constellations. In most cases chemical reactions are not complete without an ensuing chemical equilibrium that depends on the temperature. In almost all chemical reactions heat is released or absorbed. In 1912 Walther Nernst was able to formulate the third law of thermodynamics, which made it possible to calculate chemical equilibriums on the basis of the heat exchange. He achieved this by studying conditions at very low temperatures.
