You have a porous particle used for a first order reaction with a k = 6.32 min-1 and an effective diffusivity = 3.5 10-4 cm2/min. The concentration of the reactant A at the surface is 100 mM i. Use Excel or some other software to plot the Internal Effectiveness Factor (I) and the concentration of A at the center of the catalyst as a function of catalyst diameter (10 m 1000 m). ii. Construct same plot except with a rate constant four times as great (25.28 min-1). iii. Construct same plot except with a rate constant one-fourth as great (1.58 min-1).
