The reaction of ethyl-tetrabromide with zinc dust proceeds as shown in the figure below.

The reaction is C2H2Br4 + 2Zn ? C2H2 + 2ZnBr2. Based on one pass through the reactor, 80%
Of the C2H2Br4 is reacted and the remainder recycled. On the basis of 1000 kg of C2H2Br4 fed to the reactor per hour, calculate:
A) How much C2H2 is produced per hour (in kg).
B) The rate of recycle in kg/hr.
C) The feed rate necessary for Zn to be 20% excess
D) The mole ratio of ZnBr2 to C2H2 in the final products.
