Question

Problen 1 1. For production of penicillin (CIGHsO4N S, molecular weight 334.4 g/mol), glucose CoHr2O) is used as substrate and phenylacetic acid (C H O2) is added as precursor. The stoichiometry for overall synthesis is: A supply of 100 mol/hr of glucose is fed to a continuous stirred-tank reactor for the production of penicillin, along with 200 mol/hr of ammonia (NHs),130 mol/hr of oxygen, 125 mol/hr of sulfuric acid and 100 mol/hr of phenylacetic acid. a. Determine the limiting reactant in the process. (5 points) b. Calculate the percent excess molar ε% of the reactant that is in largest excess (ie. has the largest nAal). (5 points) e. Assuming 85% conversion of the limiting reactant, find the reaction rate. (5 points) d. Determine the daily production of penicillin, in Kg/day. (5 points) Problemn 2 Recycling of resources is essential for long-term space missions. For example, water is distilled from many sources, including the astronauts urine. Some of this water from the distillation system is used to produce oxygen and hydrogen gases by electrolysis. Oxygen is returned to the cabin; in current designs, the hydrogen gas is vented from the spacecraft. Another gas that is currently vented from the spacecraft is carbon dioxide. Research is ongoing to recycle both the hydrogen and carbon dioxide gases. One design under development is a Methane Formation System (MFS) (Figure 1). With an appropriate catalyst, CO and H2 react to form water and methane gas (CH). The water can then be sent to the electrolysis unit for O recovery. The H gas from the electrolysis unit, rather than being vented, is sent to the MFS as the exclusive source of Ha The goal is to produce 10.0 mol O/hr in the electrolysis unit from water sent directly from the MFS. Assume 20.0 mol/hr of CO is supplied to the MFS and that all water in the electrolysis unit is converted to O2 and Ha. For this problem, assume that any excess reagent can be vented from the MFS a. Write out balanced chemical equations for the electrolysis reaction and the methane formation reaction. (5 points) MFS unit. (5 points) electrolysis unit. (5 points) b. Determine the limiting reactant, reaction rate, and molar flow for all constituents for the c. Determine the limiting reactant, reaction rate, and molar flow for all constituents in the
