Which scientist won the 1901 Nobel Prize in Chemistry for work on chemical dynamics and osmotic pressure?

Jacobus Henricus van 't Hoff won the 1901 Nobel Prize in Chemistry for his work on chemical dynamics and osmotic pressure.

Van 't Hoff helped establish physical chemistry as a distinct discipline. His studies connected reaction rates with temperature and concentration, while his work on dilute solutions led to the van 't Hoff equation for osmotic pressure.

The award was the first Nobel Prize in Chemistry. A common mix-up is to attribute this prize to Svante Arrhenius, who won the Chemistry Nobel in 1903 for his electrolytic dissociation theory. Van 't Hoff also made influential contributions to stereochemistry by proposing the tetrahedral arrangement of carbon bonds.

His osmotic-pressure work helped scientists estimate the molecular masses of substances in solution. The prize therefore recognized a broad theoretical framework rather than one single laboratory discovery.
