what is the derived equation and the volume for this second order reqction ?

The exothermic reaction 2AB The second order (rA=kcA2) reaction is carried Out in a Tubular reactor (PFR) in which the volumetric flow rate v, is constant and entering molar flow rate is 240mol/hr 21. Derive an equation relating the reactor volume to the entering and exiting concentrations of A, the rate constant k, and the volumetric flow rate v. 2. Determine the reactor volume necessary to reduce the exiting concentration to 15% of the entering concentration when the volumetric flow rate is 16dm3/min and the specific reaction rate, k. is 0.20min1
