Chemical Reaction Engineering. Chapter 3, Part 2: Reaction Stoichiometry: Batch. Why Stoichiometry?. If we have Then we can size a number of CSTR and PFR reaction systems To find -r A = f(X) Need the rate law, -r A =f(C A , C B )

Chemical Reaction Engineering Chapter 3, Part 2: Reaction Stoichiometry: Batch
Why Stoichiometry? • If we have • Then we can size a number of CSTR and PFR reaction systems • To find -rA= f(X) • Need the rate law, -rA=f(CA, CB) • Need the reaction stoichiometry, CA=CA0(1-X) [Liquid Phase] X !!
