Question 1

Calculate ΔrG for the evaporation of methanol at 25°C under nonstandard conditions when P_CH3OH = 10.0 mbar

CH3OH(l) → CH3OH(g)

◦ +4.3 kJ mol-1
◦ -11 kJ mol-1
◦ +16 kJ mol-1
◦ +5.7 kJ mol-1
◦ -7.1 kJ mol-1

Question 2

Which of the following is true for ΔrG?
◦ If ΔrG < 0, the reaction is spontaneous in the reverse direction.
◦ If Q = 1, then DrG > ΔrG.
◦ If ΔrG ≠ 0, the reaction is spontaneous in both the reverse and forward directions.
◦ If ΔrG > 0, the reaction is spontaneous in the forward direction.
◦ Under equilibrium conditions, ΔrG = 0.
