Fuel cells provide electrical power for spacecraft (as in the NASA space shuttles) and also show promise as power sources for automobiles. Hydrogen and carbon monoxide have been investigated for use in fuel cells, so their solubilities in molten salts are of interest. Their solubilities in a molten NaNO3/KNO3 mixture were found to fit the following expressions:logs(H2)=-5.39-(980/T) logs(CO)=-5.98-(980/T)where s is the solubility in mol/cm3bar. Calculate the standard molar enthalpies of solution of the two gases at 570 K.
