Excess free energy of solid solutions of kr-ch4 mixtures at 90·67°k

The excess free energy of the solid system Kr-CH4 has been determined from ‘frost-point’ pressure measurements at 90·67° K, the triple-point temperature of pure CH4. A new method of calculating gE(x) from the experimental ‘frost curve’ P(y) has been used. The results are in good agreement with those deduced from the average potential theory of solutions. © 1961 Taylor & Francis Group, LLC.SCOPUS: ar.j
