A stream contains a waste chemical, W, with a concentration of 1mol/ liter. To meet Environmental Protection Agency and State standards, at least 90% of the chemical must be removed by reaction. The chemical decomposes by a second-order reaction with a rate constant k=1.5 liter /(molhr). The stream flow rate is 100 liters/hour and the volume of the liquid in the CSTR does not change. a. Write the modeling equations for the concentration of the waste chemical. Assume constant volume and constant density. Let: CWW= concentration in reactor, mol/ liter F= volumetric flow rate, liter /hr V= liquid volume in reactor, liters k= second order rate constant, liter /(mlhr) b. Develop a MATLAB code to simulate the dynamic reactor process. Plot the results and find the steady-state molar concentration of W in the exit stream if the volume of the liquid in the tank is 6,400lt. Is the specification met?
