Abstract
The enthalpies of the formation and decomposition of hydrogen trioxide are estimated from the heating curves of peroxide-radical condensates synthesized from gaseous O2 + H2 mixtures. Enthalpy of decomposition Н2О3(aq.) → Н2О(liq.) + О2(gas) is −31.2 ± 1.5 kcal/mol, and enthalpy of formation ΔfH(H2O3, aq.) =–37.5 ± 1.6 kcal/mol. Both values correspond to the temperature range of 240–265 K.
