4. The liquid phase reaction A + B - P with a rate expression kCCO takes place in a jacketed batch reactor. Using steam as the heating medium, the reaction mixture is heated to help the reaction start. Subsequently, the reaction proceeds adiabatically. During operation, the reaction mixture temperature should not exceed 105C in order to prevent product decomposition. To help keep the reaction temperature below 105C.cooling water can be used in the reactor jacket. For practical reasons, e.g. emptying and refilling the reactor jacket, etc. heating and cooling intervals must be separated by at least 10 minutes of adiabatic reaction. For the same reasons it is desirable to operate with as few heating and cooling intervals per batch as possible. (1) Develop a heating/cooling schedule (ii) Calculate and plot the temperature and conversion profiles.
