A steady-state PFR reactor consists of a first-order reaction of A B, and the reaction rate is-\ r A = ? CA , where ? is 0.2 min -1 . Inlet concentration of A is 0.5 mol/L, and the volumetric flow\ rate is 2 L/min. Derive a design equation for this ideal steady-state PFR. Calculate the volume of\ the plug flow reactor needed to achieve 75% conversion of A. Discuss how the reactor volume\ would change if the desired conversion were increased to 90%
