蟻, 蟻ijk, and u, uijk data of binary and ternary mixtures have been measured at 293.15, 298.15, 303.15, 308.15 K.
The measured data have been employed to determine VE, VijkE and 魏SE, (魏SE)ijk values.
The observed data have also been analyzed in terms of graph theory.
Graph theory correctly predicts the sign as well as magnitude of VE, VijkE and 魏SE, (魏SE)ijk.
