Question: The recycle system in Figure has a well-mixed, isothermal, constant volume reactor and subsequent separation unit, in which the unreacted feed is separated from the product and returned to the reactor. A single step change occurs in the reactor temperature, which can be considered a step in the rate constant of the first-order reaction. Model the system and determine and compare the dynamics for two operating methods.
a) The flow FA is constant.
a) The flow FAT is constant.
