Interpretation:
The model for a second-order reaction that takes place in a real reactor is to be proposed and the values of the model parameters,
Concept introduction:
Real reactor is defined as the process vessel which is used to perform a chemical reaction. It is modeled by various combinations of ideal reactors. The conversion, X can be defined as the moles of any species A that are reacted per mole of A fed in the reactor.
The full form of CSTR is Continuous-Stirred Tank Reactor. This reaction has its application in the industrial processes. This reactor actually used for liquid-phase reactions.
The full form of PFR is Plug-Flow Reactor which consists of a cylindrical pipe and it is used for the gas-phase reactions. It is also known as tubular reactor.
