The irreversible liquid phase reaction between reactants A and B to form products Pand T is investigated in a laboratory continuous stirred tank reactor with volume equalto VR:A+B→)P+TA chemical solution of A of concentration CA.sol and volumetric flowrate QAsol is mixedwith a chemical solution of B of concentration and volumetric flowrate QB.solforming a new solution that enters the reactor.A measuring instrument measures aproperty G of the reactor outlet solution.Only reactant A and product P contribute tothe measured property according to the calibration equation:G=AA CA+AP CPwhere G is the measured property of the solution in arbitrary units (a.u.),CA,Cp arethe corresponding concentrations of components A and P in mol L1 and A,Ap are thecalibration factors with regard to the concentrations of A and P respectively.a)Derive a relationship for the individual outlet concentrations of each component asa function of G and the process variables,QA.sol,QB.sol,CA sol, and VR only.Therelationship should include no other concentrations.5b)Derive also a relationship between reaction rate r and G (no concentrationsinvolved;only the concentrations already provided,CA.sol,CB.sol)5c)In order to estimate the reaction kinetics,experiments were carried out at differentflowrates of the two feed solutions of reactants A and B with correspondingconcentrations CA.sol 0.2 mol L-1 and CB.sol 0.2 mol L1.The volume of theexperimental reactor was VR=1 L.The values of the measured property G for each experiment are given below:Experiment1234Volumetric Flowrateof solution A,QA.sol /(L s-1)0.0100.0150.0200.025of solution B, /(L s-1)0.0100.0150.0200.025Gx103/a.u.13.61014.44715.08915.554Using the results obtained from parts a)and b),calculate the corresponding values ofreaction rate and reactant concentrations in all four experimental runs and present theresults in the form of a table.From calibration measurements it was found that2A=0.195and2p=0.070.115d)Assuming power law reaction kinetics and performing linear regression,estimatethe total reaction order and the kinetic constant (reaction rate constant).Tabulate your calculation results and present the regression plot.115e)Explain your experimental strategy in order to estimate the individual reaction orderswith regard to A and B,as well as the kinetic constant.110
