Question
The following equilibrium isothermal reaction (liquid phase) occurs in a CSTR:
A + B C + D
Reaction term in Damkohler number (Da) for above reaction can be defined as kACA0CB0. The reactions (forwards and backwards) can be assumed elementary (1st order wrt all reactants and products). AS a result, reaction rate is
rA = (kA)(CA)(CB) - (k-A)(CC)(CD)
If the equilibrium constant (Kc) is 1 and intial concentrations are
Cao = Cbo and Cco = Cdo = 0
What is the conversion of A for above equilibrium reaction in a CSTR if Da=2?
Explanation / Answer
A + B ? C + D
both forward and backward reactions are elementary
ra= kaC aCb - k-aCc Cd
Initial conc Cao = Cbo and C co = Cdo = 0
For chemical reaction A ? B of nth order, the Damk
