(C9H12) IS produced from (9H92) propylen main intermediate in a process that generates the majority of phenol and acetone globally. Please see the diagram for this continuous steady-state process below. Cumene synthesis (Reaction 1) occurs in the gas phase within a reactor with an immobilized catalyst. The main undesired product. are diisopropylbenzenes (Reaction 2). To reduce undesired reactions, benzene enters the reactor at 325% molar excess. Following the reactor, the effluent enters a condenser where the excess benzene and propylene are retrieved as the vapor product and recycled back to mix with fresh benzene and propylene before entering the reactor. The liquid product is composed of cumene and diisopropylbenzenes that then proceed to additional separation units. Reaction 1: C,Ho(8) + C3H6 (g) → C9H12 (8) Reaction 2: C,Ho (g) + 2 C3H6 (g) → C12H18 (8) a) as Sime that a' it ider vi hat th s inf f 38 ai on cti 1 or di du b) Calculate the standard heats of reactions for Reactions 1 and 2. Please note that the standard heats of formation for C9H12 (g) and C12H18 (g) are 3.90 kJ/mole and -76.51 kJ/mole, respectively. Please calculate the rate in kW at which heat needs to be supplied or removed from the reactor to ensure that it operates isothermally. Please approximate the constant pressure heat capacity of diisopropylbenzenes with that of toluene and use the heat of reaction method for this energy balance.
