By gmagoon:

I reread the manual more closely and the manual has the same syntax for other reactions formats as for PLOG where they specify cal/mol for units, suggesting that there is nothing special about the PLOG case.
For reference, here is another relevant section from the MFC manual:

Unless modified by options specified on the REACTIONS line or in Auxiliary Reaction Keywords,
the default units for Ai are in cgs (cm, sec, K, mole), the exact units depending on the reaction.
The factor is dimensionless. The default units for the activation energies are cal/mole.

So, contrary to my initial interpretation, I now interpret the manual to be saying that the units of Ea in PLOG are overridden by the overall file units. That's not to say that I believe that this is necessarily what Chemkin does, particularly since there seems to be a persistent belief in our group that there is something special about PLOG Ea units. It will be interesting to see what the tests turn up...
