Use the thermodynamic data provided below to determine ΔG (in kJ/mol) for the condensation of C3H7OH at 102.93 °C if the initial partial pressure of C3H7OH is 1.03 atm. Report your answer to one decimal place in standard notation (i.e. 123.4 kJ/mol). Substance ΔH°f (kJ/mol) S° (J mol-1K-1) C3H7OH (l) -302.5 192.8 C3H7OH (g) -255.6 322.5
