CHE 4473 (Kinetics) Test #2, 11/8/05 Name _____________________________ Instructions: Work all problems, stating any assumptions. OU Honor Council Integrity Pledge: On my honor, I affirm that I have neither given nor received inappropriate aid in the completion of this exercise. Signed:______________________________________ Date:_____________________ 45 pt. 1 . An ideal PFR is being used to carry out a liquid phase, irreversible endothermic reaction. The reactor tube has a diameter of 4 cm. Heating fluid in the shell around the reactor tube flows countercurrently with the reactant, as shown in the diagram. A + B products r = kC A C B H r = 3 x 10 5 kJ/kmol A The reaction rate coefficient k = 6.6 m 3 /(kmol·min) at 60 C. The feed concentrations of A and B are 2.0 kmol/m 3 and 1.0 kmol/m 3 , respectively. The total feed volumetric flow rate is 1.4 m 3 /min. The heat capacity and density of the reactant/product are constant and equal to 4 kJ/(kg·K) and 900 kg/m 3 , respectively. The heat transfer coefficient between the reaction mixture and heating fluid is 400 kJ/
