Question 3 of 4 Incomt Sapling Learning Map Chlorobenzene, a compound used in pesticide production, is frequenty produced by the following reaction carried out in the presence of Ala AICI 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 a reactor by two separate streams, each at T-25°C. The chlorine gas stream is fed into the reactor at m1 = 4.80 kg/s. The molar flow rate of benzene, n2, enters the reactor in a stoichiometric amount. The reaction is carried out at T 31.0 , and 1 atm. The fractional conversion of benzene is 0 790 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 moles of each species leaving the reactor and the rate of heat that is removed or added to keep the product at 31.0. The heat capacity of liquid chlorobenzene is 0.15504 kJ/(mol-K). The heat of this reaction is A,=-129.8 kJ/mol What is the rate of chlorine gas leaving the reactor? Incorrect.

Explanation / Answer

Given ,

Chlorine gas = 4.8 Kg/s = 4800 g/s

Moles of chlorine = 4.8/70.96 = 67.69 moles

Molar flow rate of benzene = 67.69 moles

Fractional conversion = moles reacted/moles fed = 0.79

No of moles of Benzene reacted = 0.79 * 67.69 = 53.475 moles/s

Moles of benzene unreacted that will be leaving the reactor at 31 degree centigrade = 67.69 - 53.475 = 14.21 moles

Number of moles of chloro benzene leaving the reactor is 53.475 moles
