Abstract:

We present calculations of time behavior of the H₂O concentration in reaction between the ozone and molecular hydrogen in a three-component mixture with nitrogen as a buffer gas. It is shown that at the reaction constant equal to 3x10¹³x exp(-3000/T) cm³/(mol×s) and proportion of partial pressures in the three-component mixture H₂:О₃:N₂ = 1:1:10000 at the total pressure being 1 atm, the reaction time increases to 1.5 s and the yield of H₂O molecules reaches 2×10¹⁵ cm^-3. We propose to use the isotopic ozone molecule¹⁸O₃ in the experiment. This would allow a reliable recording of H₂¹⁸O to be performed with any spectrometer having sensitivity no less than 10^-6 cm^-1.
