Inherent pitfalls in the simplified evaluation of kinetic curves.
It is shown and explained in detail by four examples generated from known kinetic models that simplified evaluation procedures--initial rate studies, individual exponential curve fitting method--may inherently lead to inappropriate chemical conclusions, even in the case of relatively simple kinetic systems. It is also shown that in the case of all four examples the simultaneous curve fitting immediately reveals the defectiveness of the kinetic model obtained from the simplified evaluation procedures. We therefore propose the extensive usage of the simultaneous curve fitting of all the kinetic traces to avoid these pitfalls and to find the appropriate kinetic models.
