Chapter 6 Design for Single Reaction In this chapter we deal with single reaction.These are reactions whose progress can be described and followed adequately by using one and only one rate expression coupled with the necessary stoichiometric and equilibrium expressions. For such reactions product distribution is fixed; hence,the important factor in comparing design is the reactor size.1 Chapter 6 Design for Single Reaction In this chapter we deal with single reaction.
