Engineers Julie and Walter operate a reactor where two unbalanced, gas phase reactions occur: CH3COOH+H2→C2H5OH+H2O and C2H5OH→(C2H5)2O+H2O. In the first reaction, acetic acid (CH3COOH) and hydrogen (H2) react to produce ethanol (C2H5OH) and water (H2O); and ethanol decomposes to diethyl ether ((C2H5)2O) and water in the second reaction. A stream of 67.8 mol/s hydrogen and the balance acetic acid at 147°C is fed to the reactor, which operates at steady state. The stream exiting the reactor contains acetic acid, hydrogen, ethanol, water, and diethyl ether at 417°C. The component flow rate of acetic acid exiting the reactor is 3.81 mol/s. The fraction conversion of acetic acid is 71.6%, and the selectivity, which is the ratio of the amount of ethanol to diethyl ether in the exiting stream, is 3.14. Assume all components are in the gas phase and no phase changes occur in the reactor. Find the component molar flow rate of acetic acid(AA) entering the reactor.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
