(a)
Interpretation:
The derived expressions for the concentration profile and effectiveness factor for the cylindrical pellets by assuming the first-order isomerization are to be stated.
Concept introduction:
The effectiveness factor is the division of the average rate of the reaction with rate of reaction at the bulk-stream point that is at boundary conditions or without diffusion. It is denoted by
(b)
Interpretation:
The rework of problem
Concept introduction:
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.
The conversion, X can be defined as the moles of any species A that are reacted per mole of A fed in the reactor.
