-Assignment needs to be coded in Python.

1. The liquid phase reaction A4  B is to be carried out isothermally in a continuous flow reactor.The entering molar flow rate is 5 mol/min, and the volumetric flow rate is 10 L/min. The reaction rate is given by —rA —— kCA where k —— 0.01 1/min. It is desired to consume 99% of A. Calculate the volume of the plug flow reactor and CSTR necessary for this operation.

2. For the above reaction and conversion, what is the time required in a constant volume batch reactor of volume 1000 L and CA0 —— 0.5 mol/L.

3. Consider the following experimental data for A4  C. Assume that the molar flow rate of A is 0.4 mol/s for an isothermal steady state operation of reactors. Calculate the volume of plug flow reactor and CSTR needed foF 75% conversion.

4. For the above rate data, calculate the time required for conversion in batch reactor for a conversion of 75%. Assume Can —— 1 mol/L.
