modelArrheniusEquation
Arrhenius equation y = A*exp(-(Ea/RT)^b)
Extends from PartialHenrysLawCoefficient.
Information
This model returns the coefficient kHs using the equation:
kHs = kH0*exp(-Ea/(R*T)^b)
If pre-defined data parameters are to be used then specify the row number of the desired substance(s).
