A simple approach has been used to calculate the excess entropy of mixing (ΔSxS) of liquid Na-K and Na-Cs alloys as a function of concentration and temperature The basic ingredients are the entropy of pure liquid metals and the observed volume of mixing. The temperature dependence ΔSXS for Na-Cs is strikingly diffierent than Na-K- HΔSxs for Na-Cs first increases with T and then starts decreasing whereas for Na-K it decreases continuously with increasing T above Tm.
