COMMENTS:

Served as an optimization variable in GRI-Mech 3.0 release. Optimization revealed a strong correlation between rate coefficients of reactions
54. H + HCO + M -> CH2O + M and
58. H + CH2O -> HCO + H2,
based on optimization targets from Eiteneer et al. (1998) The rate coefficient was not changed.
