WebExpressions for r must be determined from experiment. Typically, r depends on the concentration of the substance of interest, as well as the concentrations of other substances with which it reacts; e., for a reaction between A and B to form product P, the rate of “generation” of A might be given by: rA = − kc cA B. ... Batch reactors are ... WebModels the real reactor as a number of small batch reactors, each spending a different time in the reactor. All molecules that spend the same length of time in the reactor (i.e., that are of the same age) remain together in the same globule (i.e., batch reactor). Mixing of the different age groups occurs at the last possible moment at the ...
