The V<sup>Esup>, H<sup>Esup>, 魏<sub>Ssub><sup>Esup>, and C<sub>Psub><sup>Esup> data have been measured over entire mole fraction at 4 temperatures.
The V<sup>Esup>, H<sup>Esup>, 魏<sub>Ssub><sup>Esup>, and C<sub>Psub><sup>Esup> data have been fitted to the Redlich–Kister equation.
The observed data have been analyzed in terms of the Graph theory.
The V<sup>Esup>, H<sup>Esup>, 魏<sub>Ssub><sup>Esup>, and C<sub>Psub><sup>Esup> values predicted by the Graph theory compare well with experimental values.
