The master equation for the thermal dissociation and vibrational relaxation of H2infinitely dilute in mixtures of He and Ar was solved using rotationally averaged rate constants from previousabinitiostudies on H2/He and H2/Ar. The calculated rate constants for dissociation,kd, vibrational relaxation times, tgr;, and induction times for dissociation,ti, for the mixtures were compared to those predicted by the linear mixture rule:kLMR=Sgr;ixiki, wherexiis the mole fraction of gasiandkiis the rate constant for the process in pure componenti. Substantial deviations were found to occur, with the greatest deviations occurring forkd. Further analysis indicates that the deviations arise due to differing efficiencies for multiquantum transitions in H2/He and H2/Ar.
