  1. In all cases, T is temperature and k1, k2, k3 are equation-specific constants. All constants labelled as k1 are either multiplying constants as defined above in the main text, or they are rate constants (when the associated function has units). This difference is not relevant as long as they do not depend on temperature (hence, becoming a variable).
