10.37 Chemical and Biological Reaction Engineering, Spring 2007 Prof. William H. Green Lecture 1: Preliminaries & Remembrance of Things Past This lecture covers: reaction stoichiometry, lumped stoichiometries in complex systems such as bioconversions and cell growth (yields), extent of reaction, independence of reactions, measures of concentrations, single reactions and reaction networks, and bioreaction pathways. F A F o Figure 1. A schematic of a control volume with inflow of F o and outflow of species A, F A . F = total molar flow rate (moles/sec) F o = total molar flow rate entering control volume F A = molar flow rate of species A F Ao = molar flow rate of species A entering control volume N A = Moles of species A Mass balance: (change in “A” inside control volume)= (amount of “A” that entered)- (amount of “A” that exited) + (amount of “A” created inside the control volume) – (amount of “A” destroyed inside the control volume) [] dN A =− FF + G dt Ao A A moles G A = sec If homogeneous, Gr AA = V else, = d V
