Problem 1 The chemical potential of liquid acetylene at the triple point is zero.

a) Calculate the chemical potential of solid acetylene at its triple point.

b) Calculate the potential of the vapor at 0.1 atm, - 84°C.

c) State and justify your assumptions. Additional data at the triple point:

Ttriple = -84 °C, Ptriple = 1.3 atm, V solid = 34 cm³/mol, Vliq = 42.7 cm³/mol, Vvap = 12,020 cm³/mol.
