<strong>ChE</strong> <strong>321</strong>: <strong>Kinetics</strong> <strong>and</strong> <strong>Reactor</strong> <strong>Design</strong>(Due: January 30, Wednesday)1. In the class, I have explained how to derive the following Equation 1 by doing themole balance on the PFR,dF idzDerive Equation 2 from Equation 1.= A r i (Equation 1)dV=F iodx i(Equation 2)-r i[ F i =molar flow rate of species “i,” z = direction of flow, A = cross sectional area ofthe reactor, r i =reaction rate of species “i.”]2.
5. For the flow reactors, the space time is defined as τ = V/ν, where V is the volumeof reactor <strong>and</strong> ν is the total volumetric flow rate. For PFR, its space time can beexpressed as following:C Aτ = -∫dC A(Equation 3)-rAC AoC AoPlease derive Equation 3 starting from the ideal design equation of PFR.
