Tsang, W., and Hampson, R.F. (1986) J. Phys. Chem. Ref. Data 15, 1087.

In the GRI-Mech 1.1 release, the efficiency of water was 17. In the GRI-Mech 1.2 and 2.1 releases, the efficiency of water is 12.

COMMENTS:

Served as an optimization variable in GRI-Mech 1.1, 1.2, and 2.1 releases. As a result of optimization round 1.1, the preexponential factor was increase by 1.41. However, in subsequent optimization rounds, 1.2 and 2.1, the rate coefficient was returned to the original value reported above.
