### mass-transfer coefficient

Overall mass-transfer coefficient K_{G} for uptake of reactive gases by surface
water (in the absence of interfacial mass-transport limitation) for
non-reactive gases (β = 1) as a function of solubility for values of k_{G} and k_{L}
indicated on the asymptotes of the curves. Scale at right permits comparison of
interfacial and overall conductance for indicated values of the
mass-accommodation coefficient α. Also shown are Henry's law coefficients H
(open circles) and effective Henry's law coefficients H* (filled circles) of a
number of atmospheric gases; the intermediate abscissa scale gives H and H* in
units of mol kg^{-1}/(10^{5} Pa) per atmosphere favored by chemists.
