“…For the same purpose, the rate constant of reaction (2) in the kinetic equation can be replaced with its analytical expression k 2 = αl m 2k 5 V 1 /x 2 m , which is obtained by solving the quadratic equation following from the reaction rate extremum condition ∂V 3,4 (1 : 1 Adduct)/∂x = 0, where V 3, 4 (1 : 1 Adduct) = V 3 + V 4 . After these transformations, the overall formation rate equation for the 1 : 1 adducts R 3 A and R 3 B (which may be identical, as in the case of R 3 H [5,8,9,12,13,[18][19][20][21]), appears as…”
