Design of Ideal Reactors

Ideal reactors behave as reactors for which very simplified assumptions are met. These assumptions concern the dimension(s) over which change occurs these dimensions can either be time or concentration, or both. Three types of ideal reactors are known  

It can be readily discerned that the reactor equation for the batch reactor (5.12) and the plug-flow reactor (5.13) are identical. In the former, the concentration changes with time, in the latter, with location. In contrast to the situation in the other two ideal reactors, the residence time T in a CSTR is only an average, as every volume element has a different residence time throughout the reactor.
