Effectiveness Factors for Sucrose Inversion in Ion Exchange Resins

Example 3jSJ -2 Effectiveness Factors for Sucrose Inversion in Ion Exchange Resins 

The pellet diffiisivity was also sqiarately measured, in the Na resin form D, = 169 X 10 cm s. More exact values for the resin form were also conqiuted from the reaction data, but as an oample of the estimation of an effectiveness frmtor, the Na value will he used here. 

Gilliland et al. also determined rate constant values at 60° and 70 Q and the observed activation energies were 

The activation energy for diffusion was about 6 to 10 kcal/mol (25-42 kJ/mol) and so in the strong pore diffusion limitation region with d, = 0.17 mm., the predicted falsified activation energy is
