The Algorithm for Data Analysis

For batch systems, the usual procedure is to collect concemration time data, which we then use to determine the rate law. Table 5-1 gives the procedure we will emphasize in analyzing reaction engineering data. 

Data for homogeneous reactions is most often obtained in a batch reactor. After postulating a rate law and combining it with a mole balance, we next use any or all of the methods in Step S to process the data and arrive at the reaction orders and specific reaction rate constants. 

Analysis of heterogeneous reactions is. shown in Step 6. For gas-solid heterogeneous reactions, we need to have an understanding of the reaction and possible mechanisms in order to postulate the rate law in Step 6B. After studying Chapter 10 on heterogeneous reactions, one will be able to postulate different rate laws and then use Polymath nonlinear regres.sion to choose the best rate law and reaction rate parameters. 

The procedure we should u.se to delineate the rate law and rate law parameter is given in Table 5-1. 

Select reactor type and corresponding tnolc balance.
