3. The reaction of ethyl-tetrabromide with zinc dust proceeds as shown in the figure below: The reaction CH,Br, + 2Zn →C,H, + ZnBr,. Based on one pass through the reactor, 80% of the C:H;Bra is reacted and the remainder recycled. On the basis of 1000 kg of C;H;Bra fed to the reactor per hour, calculate: a. How much CHz is produced per hour (in kg)? b. The rate of recycle in kg/hr c. The feed rate necessary for Zn to be 20% in excess d. The mole ratio of ZnBrz to CHz in the final products Zn Reactor Separator C2H2Bra > ZnBr2 Recycle, R: CaH2Br4 VERS
