Concentration dependences of the isobaric heat capacity of binary solutions and its contribution to thermal calculations

The concentration dependences of the isobaric molar heat capacity of binary homogeneous nonelectrolyte systems have been analyzed. The temperature effect on the isobaric molar heat capacity has been evaluated. The possibility of replacing the isobaric heat capacity of nonideal binary mixtures with additive values when calculating the heat balances of distillation columns has been discussed.
