Transcribed Image Text:Below is a graph of the enthalpy change on mixing for the binary mixture
of trichloromethane (x1) and ethanol (x2) at 30 °C. The values are in J/mol. At this
temperature the pure molar enthalpies of each component are equal to zero.
a) At a mixture of x1 = 0.1, determine whether or not the partial molar enthalpies of
each component ( H, and H,) are greater, less than, or equal to zero.
b)
At a mixture of x1 = 0.5, determine whether or not the partial molar enthalpies of
each component ( H, and H,) are greater, less than, or equal to zero
