| Abstract: | The activated complex as a transition state in the chemical kinetic processes is actually at a nonequilibrium steady state. By means of the stochastic theory of nonequilibrium thermodynamics the thermodynamical and the statistical problems concerned with the absolute rate theory are commented. The influences of both the dissipation and the fluctuation in activated complexation on the reaction rate are analysed quantitatively. As a result a revised explicit statistical formula of the rate constant has been deduced. |
