Jacobus Henricus van 't Hoff Jr. (Dutch: [vɑn (ə)t ˈɦɔf]; 30 August 1852 – 1 March 1911) was a Dutch physical chemist. A highly influential theoretical chemist of his time, 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. In his 1874 pamphlet, Van 't Hoff formulated the theory of the tetrahedral carbon atom and laid the foundations of stereochemistry. In 1875, he predicted the correct structures of allenes and cumulenes as well as their axial chirality. He is also widely considered one of the founders of physical chemistry as the discipline is known today.

👉 Jacobus Henricus van 't Hoff in the context of Arrhenius equation
In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates. The equation was proposed by Svante Arrhenius in 1889 on the basis of the work of Dutch chemist Jacobus Henricus van 't Hoff, who had noted in 1884 that the Van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and reverse reactions. This equation has a vast and important application in determining the rate of chemical reactions and for calculation of energy of activation. Arrhenius provided a physical justification and interpretation for the formula. Currently, it is best seen as an empirical relationship. It can be used to model the temperature variation of diffusion coefficients, population of crystal vacancies, creep rates, and many other thermally induced processes and reactions. The Eyring equation, developed in 1935, also expresses the relationship between rate and energy.
The temperature dependence arises because a greater fraction of molecular collisions have sufficient energy to exceed the activation barrier as temperature increases.

Jacobus Henricus van 't Hoff in the context of Nobel Prize in Chemistry
The Nobel Prize in Chemistry is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895, awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. This award is administered by the Nobel Foundation and awarded by the Royal Swedish Academy of Sciences on proposal of the Nobel Committee for Chemistry, which consists of five members elected by the academy. The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death.
The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands, "for his discovery of the laws of chemical dynamics and osmotic pressure in solutions". From 1901 to 2024, the award has been bestowed on a total of 195 individuals. The 2024 Nobel Prize in Chemistry was awarded to Demis Hassabis and John Jumper for protein structure prediction and to David Baker for Computational Protein Design. As of 2022, eight women had won the prize: Marie Curie (1911), her daughter Irène Joliot-Curie (1935), Dorothy Hodgkin (1964), Ada Yonath (2009), Frances Arnold (2018), Emmanuelle Charpentier and Jennifer Doudna (2020), and Carolyn R. Bertozzi (2022).

Bernard Lucas "Ben" Feringa (Dutch pronunciation: [ˈbɛrnɑrt ˈlykɑz bɛn ˈfeːrɪŋɣaː]; born 18 May 1951) is a Dutch synthetic organic chemist, specializing in molecular nanotechnology and homogeneous catalysis.
He is the Jacobus van 't Hoff Distinguished Professor of Molecular Sciences, at the Stratingh Institute for Chemistry, University of Groningen, Netherlands, and an Academy Professor of the Royal Netherlands Academy of Arts and Sciences.

The Nobel Prize in Chemistry (Swedish: Nobelpriset i kemi) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel, who died in 1896. These prizes are awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by the Royal Swedish Academy of Sciences. The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands. Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years. In 1901, van 't Hoff received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007. The award is presented in Stockholm at an annual ceremony on 10 December, the anniversary of Nobel's death.
At least 25 laureates have received the Nobel Prize for contributions in the field of organic chemistry, more than any other field of chemistry. Two Nobel Prize laureates in Chemistry, Germans Richard Kuhn (1938) and Adolf Butenandt (1939), were not allowed by their government to accept the prize. They would later receive a medal and diploma, but not the money. Frederick Sanger is one out of three laureates to be awarded the Nobel Prize twice in the same subject, in 1958 and 1980. John Bardeen, who was awarded the Nobel Prize in Physics in 1956 and 1972, and Karl Barry Sharpless, who won the Nobel Prize for Chemistry in 2001 and 2022, are the others. Two others have won Nobel Prizes twice, one in chemistry and one in another subject: Maria Skłodowska-Curie (physics in 1903, chemistry in 1911) and Linus Pauling (chemistry in 1954, peace in 1962). As of 2023, the prize has been awarded to 192 individuals, including eight women (Maria Skłodowska-Curie being the first to be awarded in 1911).
