Chlorobenzene, a compound used in pesticide production, is frequently produced by the given reaction carried out in the presence of AICI. AICI + Cl, HCl + CI This reaction is always kept below 45 C because above that temperature, di- and tri-chlorinated benzene are products. In a particular reactor that produces chlorobenzene, chlorine gas and liquid benzene are fed into the reactor in two separate streams, each at T1 = 25 C. The chlorine gas stream is fed into the reactor at m = 3.60 kg/s. Benzene enters the reactor in a stoichiometric amount, at a molar flow rate of n2. The reaction is carried out at T2 = 41.0 C and 1 atm. The fractional conversion of benzene is 0.750. The product streams exit at the same temperature at which the reactor is running. The products consist of chemicals in the gas state (chlorine gas and hydrogen chloride) and chemicals in the liquid state (benzene and chlorobenzene). Assume that no benzene or chlorobenzene is in the gas phase. Find the molar flow rate of each species leaving the reactor and the rate of heat that is removed or added to keep the product at 41.0 C. The heat capacity of liquid chlorobenzene is 0.15504 kJ/mol.K). The heat of this reaction is All, = -129.8 kJ/mol What is the molar flow rate of chlorine gas leaving the reactor? rate of chlorine gas: mol Cl,/s What is the molar flow rate of benzene leaving the reactor? rate of benzene: mol CH /s What is the molar flow rate of hydrogen chloride leaving the reactor? rate of hydrogen chloride: mol HCl/s What is the molar flow rate of chlorobenzene leaving the reactor? rate of chlorobenzene: mol CH, Cl/s What is Q, the rate of heat either added or removed from the reactor to keep it at a constant temperature? Q is positive if heat is added; Q is negative if heat is removed. Q= kW
