Non-equilibrium dissociation rate coefficient of O2+O2 collision at high temperatures

•The non-equilibrium dissociation rate coefficients of the Boltzmann distribution for the O2+O2 reaction expand to T = 30000 K.•The dissociation rate coefficients consider all key physical processes such as centrifugal barrier, translational energy, rotational energy, vibrational energy, internal energy, and non-Boltzmann effects.•The non-equilibrium dissociation rate coefficients of the non-Boltzmann distribution of the O2+O2 reaction from T = 8000 k to T = 30000 K.•The influence of the non-Boltzmann effects for dissociation rate coefficients.
