Is CH4->C+4H a reasonable (semi-quantitative) approximation for CH4 dissociation at ~30,000K such as it would occur during lightning?

I am working on a model for the generation of thunder on Titan, including (semi-quantitatively) the dissociation/ionization of the N2-CH4 mixture. For methane, I am using the approximate reaction...
