The liquid-phase reaction follows an elementary rate law and is carried out isothermally in a flow system. The concentrations of
the A and B feed streams are 2 M before mixing. The volumetric flow rate of each stream is 5 dm3/min, and the entering temperature is 300 K. The streams are mixed immediately before entering. Two reactors are available. One is a gray, 200.0-dm^3 CSTR that can be heated to 77C or cooled to 0C, and the other is a white, 800.0-dm^3 PFR operated at 300 K that cannot be heated or cooled but can be painted red or black. Note that k = 0.07 dm^3 /mol/min at 300K and E =20 kcal/mol. Required:
a. Which reactor and what conditions do you recommend? Explain the reason for your choice.
b. How long would it take to achieve 90% conversion in a 200-dm^3 batch reactor with after mixing at a temperature of 77C?
c. What would your answer to part (b) be if the reactor were cooled to 0C?
Explanation: since oxalic acid is a weak acid it wont provide a strong acidic medium. So in order to provide a strong acidic medium dilute sulphuric acid is added.
