Ethyl alcohol heat of vaporization
WebCalculate the heat of vaporization of ethanol (ethyl alcohol), C 2 H 5 OH. The standard enthalpy of formation of C 2 H 5 OH ( l) is –277.7 kJ/mol and that of C 2 H 5 OH ( g) is –235.1 kJ/mol. Step-by-step solution Step 1 of 5 We have to calculate the heat of vaporization of ethanol. The reaction is depicted as: WebFor example, the bond enthalpy for a carbon-carbon single bond is about 348 kilojoules per mole. You might see a different value, if you look in a different textbook. However, we're gonna go with 348 kilojoules per mole for our calculation. And we're gonna multiply this by one mole of carbon-carbon single bonds.
