Ethylene gas and steam at atmospheric pressure are fed to a reaction process as an equimolar mixture. The process produces ethanol by the reaction: C2H4(g)+H2O(g)C2H3OH(l) The liquid exits the process at 25C. An amount of 120,000J heat per mole of ethanol is produced by the process. Calculate the temperature of feed to the process? Information: Heat of reactions at 25C and mean heat capacity at ideal gas state are available as in Table Q4. Table 04 . The value of R=8.314J/molK
