Jacobus Henricus van ‘t Hoff and Physical Chemistry

On August 30, 1852, Dutch physical chemist Jacobus Henricus Van ‘t Hoff was born. Van ‘t Hoff was the first winner of the Nobel Prize in Chemistry. His pioneering work helped found the modern theory of chemical affinity, chemical equilibrium, chemical kinetics, and chemical thermodynamics. He formulated the theory of the tetrahedral carbon atom and laid the foundations of stereochemistry and predicted the correct structures of allenes and cumulenes as well…
