4.1 [Maps to SO 1, 3] Monsanto produces nitroaniline (NA) from ammonia (NH;) and ortho-nitrochlorobenzene (ONCB) according to the reaction: ONCB + 2 NH3 -> NA + NH,CI This is an exothermic batch reaction normally carried out isothermally at 175 C and 500 psi. Some information: Rate Expression: -ONCB = KCONCBCNH3 k = 0.00017 m /(kmol min) @ 188 C NONCB,0 = 3.17 kmol; NH20,0 = 103.6 kmol; NNH3,0 = 43 kmol Reaction Volume: 3.26 m3 Enthalpy of Reaction: -5.9 x 105 kcal/kmol EA = 11,273 cal/mol Heat Capacities: ONCB: 40 cal/(mol K); H20: 18 cal/(mol K); NH3: 8.38 cal/(mol K) You may assume the Delta Cp = 0. For the reactor design: UA = 35.85 kcal/(min .C), with a cooling water T = 298 K available. a) Using Jupyter Notebooks, plot both conversion of ONCB and the reactor temperature as a function of time in minutes using the standard conditions listed above. Use the ipywidgets function to create a slider for both the Heat Transfer parameter (UA) as well as the cooling water temperature. 1. For the standard conditions, is there a critical value of UA where the reactor becomes uncontrollable? 2. Assuming UA is at its maximum value of ~35, are there any scenarios where the cooling water temperature makes the reactor uncontrollable? 3. Assuming you operate isothermally, how long would it take to reach 100% conversion
