Either the differential rate law or the integrated rate law can be used to determine the reaction order from experimental data. Often, the exponents in the rate law are the positive integers: 1 and 2 or even 0. Thus the reactions are zeroth, first, or second order in each reactant. WebPerhaps the simplest chemical engineering model of a chemical reaction is the CSTR — the continuous flow stirred tank chemical reactor. In the CSTR we imagine that a reactant flows into a vessel and undergoes a single heat producing reaction to form inert products. The concentration of the reactant inside the vessel is denoted by c and the ... orcad linear dimension

WebThe CSTR is always operating a the lowest concentration, the exit concentration. When say two CSTRs are in series, the first operates at a higher concentration, therefore the rate is greater, therefore the conversion is greater. The second reactor in series builds on the conversion in the first reactor.
