Mass transfer limitations can be detected through various experimental methods:
Thiele Modulus: A dimensionless number used to determine the significance of internal diffusion resistance. A low Thiele modulus indicates negligible internal mass transfer resistance. Weisz-Prater Criterion: Another dimensionless number that helps assess the significance of internal diffusion limitations in catalytic reactions. Effect of Agitation: Observing the change in reaction rate with varying levels of agitation can indicate the presence of external mass transfer resistance.
