Solution:
\begin{parts}
\part [4] What is the definition of space time ($\uptau$) based on conversion ($X$), and Damkohler Number ($Da$) in a CSTR.
\part [4] What is the conversion for a second order reaction in a CSTR by function of $Da$?
\part [5] As shown below is two CSTRs in series, to derive the equation of $C_{A1}$ and $C_{A2}$ in terms of space time ($\uptau$), kinetic constant ($k$) and input concentration $C_{A0}$ for each tank.
