  1. Lecture 8 Tuesday 1/29/08 • Block 1: Mole Balances on PFRs and PBRs • Must Use the Differential Form • Block 2: Rate Laws • Block 3: Stoichiometry Pressure Drop: Liquid Phase Reactions. Pressure Drop Does Not Effect the Concentrations in Liquid Phase Rxns Gas Phase Reactions. Epsilon not Equal to Zero d(P)/d(W)=.. Polymath will combine with d(X)/f(W)=..for you Epsilon = 0 and Isothermal P=f(W) Combine then Separate Variables (X,W) and Integrate Gas Phase Reaction. PBR Example 1: Polymath Solution A + 2B  C Gas Phase Reaction. PBR Example 2: Analytical Solution A + B  C + D

  2. Heat Effects Isothermal Design Stoichiometry Rate Laws Mole Balance

  3. 2. Rate Law: –rA=kCA23: Stoichiometry
