10. Bacteria sour wines and beers by converting ethanol, C₂H5OH, into acetic acid, CH₂COOH. Assume that the reaction is C₂H5OH(1) + O₂(g) → CH₂COOH() + H₂O(1) The standard molar enthalpies of combustion of ethanol and acetic acid to produce liquid water are, respectively, - 1367 kJ/mol and -875 kJ/mol. Write chemical equations for the combustions, and use Hess' law to determine the standard enthalpy change for the conversion of ethanol to acetic acid.
Combustion of 3.50 g of ethanol, C2H5OH(l), in a 100.0 g calorimeter with a heat capacity of 152 J/g0C causes a temperature increase from 19.88 0C to 26.18 0C. Find the molar enthalpy of combustion for ethanol from this evidence.
