Question 1

If the enthalpy of vaporization of chloromethane, CH3Cl, is 21.5 kJ/mol at the normal boiling point, 249 K, calculate ΔvapS°.
◦ 86.3 J mol-1 K-1
◦ 5.35 J mol-1 K-1
◦ 11.6 J mol-1 K-1
◦ 896 J mol-1 K-1

Question 2

If the vapor pressure of water in an open system at 25 °C is 23.8 mmHg, what is ΔrG for the reaction below at 25 °C?

H2O(l) → H2O(g, 23.8 mmHg)

◦ 0 kJ/mol
◦ -8.58 kJ/mol
◦ +8.58 kJ/mol
◦ -0.720 kJ/mol
◦ +0.720 kJ/mol
