CDP7-BB

The irreversible isomerization

A B

was carried out in a batch reactor and the following concentration-time data were obtained:

(a) Determine the reaction order,, and the specific reaction rate, kA.

(b) If you were to repeat this experiment to determine the kinetics, what would you do differently? Would you run at a higher, lower, or the same temperature? Take different data points? Explain.

(c) It is believed that the technician made a dilution error in the concentration measured at 17.5 min. What do you think? How do your answers compare using regression (POLYMATH or other software) with those obtained by graphical methods? (Ans.: (a) k=0.2 (mol/dm3)1/2/min)
