Chapter 4, Problem 4.35P

Ethylene gas and steam at 320°C and atmospheric pressure are fed to a reaction process as an equimolar mixture. The process produces ethanol by the reaction:

${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}\left(\text{g}\right){\text{+H}}_{\text{2}}\text{O}\left(\text{g}\right)\to {\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{OH}\left(\text{l}\right)$

The liquid ethanol exits the process at 25°C. What is the heat transfer associated with this overall process per mole of ethanol produced?
