For the stirred tank reactor in Example 22.8, determine whether the chosen operating/design point (T= 93.5, X = 80%, T_c,1 = 20C, T_C,2 = 30C, and A = 3.96 m²) represents a stable operating condition.

Example 22.8 An exothermic, liquid-phase reaction is to take place in a stirred tank reactor. The feed to the reactor (F) is pure A at 500 mol/min with a concentration of 10 mol/L. The volume of the reactor is 100 L, and the feed temperature is 30°C. A reaction takes place in which A is converted to B (AⓇB) by a first-order reaction: 1650 -TA = KCA = 3e TCA [mol/m³/s] СА The heat of reaction (-AH) is 75,240 J/mol, and it is approximately constant from 30°C to 200°C. Other data for the process and coolant are as follows: Data:
