Figure 4.8 Effectiveness factor ηint for
Michaelis-Menten kinetics as a
function of the Thiele modulus Φ with
the dimensionless surface
concentration βS as the parameter. The
effectiveness factor for spherical
particles and membranes is represented
by solid and broken lines respectively.

where and i is an index which varies from l to n−l. Substituting (33) and (34) in
equation (21) yields:
(35)Noting that equation (35) gives:
(36)This simple transformation allowed elimination of the 0/0 undetermination.
Analogously, for the case of reversible Michaelis-Menten kinetics:
