^†$k$ is given in units of inverse time assuming that $L_{\infty }$ and $L$ in Eq. (8) are rigorously normalized by the unit reference concentration 1 ${\text{g}}_{\text{w}}{\text{g}}_{\text{p}}^{-1}$.

^‡Pure liquid water reference state (or reference pressure of $P^{\text{o}}=P^{\text{sat}}$). Subtract the heat of condensation of water to convert to ideal gas reference state.
