How much heat is required to convert 22.8 g of liquid benzene (C6H6) at 58 âC to gaseous benzene at 100 âC? The boiling point of benzene is 80.1 âC and Cm [C6H6(l)] = 136.0 J/(molâ âC), and ÎHvap = 30.72 kJ/mol, Cm [C6H6(g)] = 82.4 J/(molâ âC).
Calculate the standard enthalpy of combustion for benzene, C6H6.
The enthalpy of formation of benzene is known [ΔHf° [C6H6(l)] = +49.0 kJ/mol], and other values needed can be found at the back of most chemistry textbooks.
