Criteria for collecting kinetic data

In general, a number of criteria can be identified that the ideal 

1 The experiment must be isothermal and uniform in chemical composition (i.e., present perfect mixing). Temperature gradients may be minimized by intensive heat exchange, dilution of the active material, or rapid recirculation of fluid phase. The reaction zone may be minimized in order to render the reactor gradientless, such as in the cases of differential plug flow reactor (Section 10.4.1.1) or thin-zone TAP reactor (TZTR) (Section 10.6.1.2). 

2 The technique must provide the ability to separate transport effects, such as pore diffusional resistance, and film mass and heat transfer, from kinetic effects. Transport should be well defined and the measurement should be conducted in a regime where surface reaction is controlling. 

4 Kinetic data should be collected over a wide range of temperature and reactant concentrations for comparison to other studies and translation to a working environment.
