Friedrich Wilhelm Ostwald ドイツ帝国 触媒作用、化学平衡および反応速度に関する研究
In the 19th century chemists noticed that certain chemical reactions seemed to be caused by substances that remained unchanged in the process.
In the 1880s Wilhelm Ostwald studied the speeds of numerous chemical reactions, including reactions occurring in the presence of acids and bases. In 1894 he revealed what happens: a substance - a catalyst - can affect a chemical reaction's speed, but is not included in its end-products. It does this by lowering the reaction's activation energy 活化能 - the energy needed to kick-off a reaction (see picture). This understanding shed great light on chemical reactions occurring in both industrial processes and living organisms and led to Ostwald receiving the 1909 Nobel Prize in Chemistry.
