Calculate the enthalpy of formation of d-threose and benzoic acid using either an arithmetic method (e. g., bond dissociation energies) or a computational method (e. g, ab initio electronic structure computational program like molcalc. org)
a sample of the monosaccharide (sugar) d-threose of mass 1.15 g was placed in a constant volume calorimeter and then ignited in the presence of excess oxygen. the temperature rose by 1.48oc. in a separate experiment in the same calorimeter, the combustion of 0.917 g of benzoic acid, for which the internal energy of combustion is -3226 kj/mol, gave a temperature rise of 1.94oc.
