Question

1.) The heat of fusion, ?Hfus, of ethanol (C2H5OH) is 4.9 kJ/mol.The heat of sublimation of ethanol, for the process C2H5OH(s) ? C2H5OH(g) , is 43.5 kJ/mol.What is the heat of vaporization of ethanol? Report your answer in units of kJ/mol2.) The heats of reaction for the following combustion reactions were determined experimentally: C2H4(g) + 3 O2(g) ? 2 CO2(g) + 2 H2O(?) ?H = -1411.1 kJ C2H5OH(?) + 3 O2(g) ? 2 CO2(g) + 3 H2O(?) ?H = -1367.5 kJConsiderig the above reactions, what is the heat of reaction for the synthesis of thanol from ethylene and water: C2H4 + H2O(?) ? C2H5OH(?) ?H = ?
