An immobilized CSTR is being used to carry out an enzymatic conversion described by A $->$ B$.$ Reactant A enters the reactor at a concentration of $1$M and with a flow rate of $5$ L$/$min$.$ For KM$=0\mathrm{.}1$ M$,$ Vmax$=2$ M min$-1,$ and neglecting mass transfer effects. Determine the mass transfer the transfer function based on the concentration $($inlet & outlet$)$ of A$?$
