The detailed chemical reaction model for H2/O2 combustion proposed by Koshi was estimated in a high pressure state. In this paper, two rate coefficients of the terminating reactions are discussed. The numerical ignition delay time in H2/O2/ Ar mixture were compared with the experiments measured by Petersen et al. and the rate coefficient of the reaction H+ O2+Ar→HO2+Ar was decided as k=2.96×1019T-140. The numerical laminar flame velocity in H2/O2/H2O mixture at various pressures is compared with the experimental data measured by Kusharin et al. The rate coefficient of the reaction H +O2+H2O→HO 2+H2O is determined as k=1.62×1023T -229.
