Energy changes in vibrational and rotational energy modes of carbonaceous molecules and that of free electron due to dissociation and recombination reactions were calculated based upon Jaffe's theory on molecular dissociation. The results were applied to the analysis of a merged shock-layer with carbon ablation to investigate the effects of the energy changes on the shock layer of a body reentering the Earth's atmosphere. The calculation was based upon a 4-temperature and 16 chemical species model. It was found the energy changes had a significant effect on flow properties in the high temperature shock layer.
