100%
Ethylene gas (25°C) and steam (30°C) and atmospheric pressure are fed to a reaction
process in an equimolar mixture. The process produces ethanol by the reaction:
C2H4(g) + H2O(g) → C2H5OH(l)
The liquid ethanol exists the process at 25°C. What is the heat transfer associated with
this overall process per mole of ethanol produced?
Standard Heat of Formation:
Delta Н°298.15 = 52,510 J/mole (C2H4(g))
delta H°298.15 = -241,818 J/mole (H2O(g))
delta H°298.15 = -277,690 J/mole(C2H5OH(l))
Cp =5/2 R for ethylene gas and Cp= 7/2 R for steam
