chemical reaction

The reaction: AB is to be carried out isothermally in a continuous-flow reactor. The entering volumetric flow rate V0 ' is 15dm3/h. 1. Calculate both the CSTR and PFR reactor volumes necessary to consume 80% of A wher the entering molar flow rate (FNO) is 6mol/h, assuming the reaction rate rA is: rA=k.CAwithk=0.0001s1 2. Calculate the time necessary to consume 90% of species A in a 1000dm3 constant-volur batch reactor with same concentration CAO used in continuous-flow reactors
