P6B.10 Fuel cells show promise as power sources for automobiles. Hydrogen and carbon monoxide have been investigated for use in fuel cells, so their solubilities, s, in molten salts are of interest. Their solubilities in a molten NaNO,/KNO, mixture were found to fit the following expressions: 768 log(s,/molcm³bar")=-5.39-K 980 log(sco/molcm³bar)=-5.98-K Calculate the standard molar enthalpies of solution of the two gases at 570 K.
