• In principle, every reaction is on the continuum between pure kinetic control and pure thermodynamic control. These terms are with respect to a given temperature and time scale. A process approaches pure kinetic control at low temperature and short reaction time. For a sufficiently long time scale, every reaction approaches pure thermodynamic control, at least in principle. This time scale becomes shorter as the temperature is raised. WebIn a kinetic method the analytical signal is determined by the rate of a reaction involving the analyte, or by a nonsteady-state process. As a result, the analyte’s …
