It is proposed to use a series of equal CSTR to convert A into R. This is a liquid reaction, the stoichiometry is AR, and the rate of reaction is given in Table 2. How many tanks would be required to reduce the concentration from CAo=1.4mol/L to CAf=0.4mol/L ? Also indicate the exit concentration from each tank. The mean residence time in each tank can be approximated to be 15min. Hint: Need to use graphical approach
