Ethylene gas and steam at atmospheric pressure are fed to a reaction process as an equimolar
mixture. The process produces ethanol by the reaction:
C,H,(g)+H,0(g) →C,H¸OH(I)
The liquid exits the process at 25°C. An amount of 120,000 J heat per mole of ethanol is produced
by the process. Calculate the temperature of feed to the process?
Information: Heat of reactions at 25°C and mean heat capacity at ideal gas state are available as
in Table 1.
