The Enthalpies of Combustion and Formation of Ortho- and Parafluorobenzoic Acid.

The enthalpies of combustion and formation of one sample of ortho- and two samples of parafluorobenzoic acids have been determined by combustion in an oxygen-bomb calorimeter. The data obtained by other investigators are discussed briefly. The values obtained and their estimated uncertainties are as follows: [Table: see text] where ΔHc° corresponds to the reaction: $C_{7} H_{5} O_{2} F (c) + 7 O_{2} (g) + 48 H_{2} O (liq) \to 7 {CO}_{2} (g) + [HF + 50 H_{2} O] (liq) .$ .
