A process to make ethanol (C2H5OH) consists of reacting pure ethylene (C2H4) with
pure water as shown in the diagram below. The ethylene gas is bubbled through
water, and the resulting ethanol-water mixture is slowly removed. Little ethylene
is converted per pass, so it is necessarily recycled to extinction. Using the extent of
reaction approach, calculate the mass feed rates of water and ethylene required.
