THE THERMODYNAMIC FUNCTIONS OF HYDROGEN PEROXIDE

Abstract

Using structural data and vibrational frequencies measured recently, the thermodynamic functions of gaseous hydrogen peroxide were calculated by the statistical method over the range 298.16 to 1500°K. at 100° intervals. Some uncertainty results from the lack of accurate information on the potential barrier hindering free rotation of the OH groups in the molecule. The equilibrium constants of a few important reactions involving hydrogen peroxide were also calculated from existing data on the heat of decomposition and the heat of dilution.
