Urea dissolved in aqueous solution is degraded to ammonia and co2 by the enzyme eads. conversion rate is controlled by transfer of urea to the surface of the beads through liquid film, and the conversion takes place on the surfaces of the beads. the following parameters are given for the system. k 0.32 cm/s; km 235 mg/l m 0 sb 950 mg urea/l a. determine the surface concentration of urea. b. l4 mg urea/cm' support surface s. determine the rate of urea degradation under mass transfer controlled conditions.
