WebIn 1836, the term ‘catalysis’ made coined by Swedish chemi Berzillius, and Ostwald in 1895 scientifically explained it when: “a catalyst speed a chemical reaction without affecting the position of the equilibrium.” In 1909, Ostwald has awarded the noble prize for his trailblazing operate in this field.
