Summary0004061: Error in implementation of Langmuir-Hinshelwood reaction rate derivative with respect to molar concentration
DescriptionLine 155 in file LangmuirHinshelwoodReactionRateI.H (last operation in function Foam::LangmuirHinshelwoodReactionRate::ddc):

ddc[r_[1]] = - k*m_[1]/b*dbdc2;

should be replaced with:

ddc[r_[1]] = - k*m_[0]/b*dbdc2;

See analytic derivation for this kind of reaction rate (equation 9 in attached pdf file) where I tried to use the same nomenclature used in the code.
