Four point charges, q, are fixed to the four corners of a square that is 12.6 cm on a side. An electron is suspended above a point at which its weight is balanced by the electrostatic force due to the four point charges, at a distance of 12 nm above the center of the square. (The square is horizontally flat, and the electron is suspended 12 nm vertically above the center of the square.) What is the magnitude of each fixed charge in coulombs?

In the derivation of rrkm theory, a factor of 1/2 is introduced when equalizing the rates of formation and decomposition of activated complex as keal-hr) = ko this is clearly against the assumption of transition state theory that states all the activated complex in the transition state iss going to the product. find the reason why this factor is introduced here.
