Document Summary
Cstr: in - out + gen = accum. I don"t think right hand side of eqn is correct. Pfr: in - out + gen = accum. The decomposition of acetaldehyde at 518 oc and 1 atmosphere was studied in a flow reactor. The reaction tube is 3. 3 cm id and 80 cm long. The flow rate through the tube is varied by changing the boiling rate. Analysis of the products from the end tube gives the results in the table below. Considering irreversible second order kinetics for the decomposition of acetaldehyde, calculate the rate constant for this reaction from the data below. Need one eqn that contains k (unknown), fa0 (measured), xa (measured), and knowns. In this case, using 2nd column of data for conversion and flow rate. The reaction a --> b occurs in solution with the rate equaiton for this reaction given as: where ca is the concentration of species a in [mol/l].
