Estimating Kinetic Parameters from a Batch Reactor .

Consider an irreversible homogeneous liquid-phase reaction taking place in a batch reactor. Assume that the experimental data (i.e. the concentration of species versus time data indicated by the blue dots in the figure) comes from, for example, the on-line measurement of electrical conductivity of the mixture in the reactor. The governing equation of the batch reactor is given by with .
