The thermal dissociation/recombination reaction of hydrogen peroxide III.: Analysis and representation of the temperature and pressure dependence over wide ranges

Experimental rate coefficients for the thermal dissociation H2O2 + (M) → 2OH(+M) and the reverse recombination 2OH(+M) → H2O2(+M) are combined with recent modelling results based on an ab initio potential energy surface. The rate coefficients derived from the complementary experimental and modelling results are represented over wide ranges of temperature and pressure, such as being of interest for practical applications. Limiting low and high pressure rate coefficients as well as detailed and simplified expressions for rate coefficients in the falloff range are given.
