WebEyring would collaborate in Berlin with Polanyi. Eyring’s stay in Berlin was short, under his National Research Council Fel-lowship. By the time Polanyi and Eyring’s first coauthored paper was published in 1930, Eyring was back in the US as a chemis-try instructor at Berkeley. In 1931 he left California for an http://www.pfigueiredo.org/MAI13.pdf
The Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature.
