2. A non-isothermal CSTR with a 1" order reaction. The tank is insulated to the environment, so there is no heat exchange with the outside. A products -r = kCA -E k = Aexp The tank is equipped heat exchanger coil. For simplicity, heat transferred between the tank and the coil is: Q = -UA(T-T.) where Te is the temperature of the coil fluid. The inlet flow only contains A at its initial steady state concentration Cao,s=1 mol/m3 and the outlet flow contains A in its initial steady state concentrations: CA,s=0.075 mol/m3. The inlet, tank, and coil initial steady state temperature is 303 K RT Data: F=0.085 m /min, V=2.1 m kis 0.5, the pre-exponential factor A is le10 1/min, and Ea is 59.75 kJ/mol -AHxn-1.3e3 kcal/mol UA=65 kcal/min C) Rho (density=1000 kg/m3 Cp=1 kcal/kg ) a. Set up the model balance equation(s) in regular variables and describe the initial conditions. b. Solve the model numerically for a step change of +20 degrees in inlet temperature, how long for the system to reach steady state? c. Solve the model numerically for a step change of -20 degrees in coil fluid temperature, how long for the system to reach steady state
