1. A change of state occurs within a system and produces 64.0 kB of heat which is transferred to the surrounding at a constant pressure and a constant temperature of 300K. For this process DSsurroundings is:
64.0 kJ
-64.0 kJ
-213 J/K
213 J/K
none of these

2. Which statement is TRUE?
DS decreases with an increase in volume
free energy is independent of volume
free energy is independent of pressure
free energy is dependent on pressure
none of the above

3. Which of these statements is false?
For a spontaneous reaction DG is negative
Independent of T, a reaction must be spontaneous if DH = 0 and DS is positive
A spontaneous reaction is always fast
A spontaneous reaction occurs without outside intervention
None of the above is false

4. Which of the following will be true when a pure substance in liquid phase freezes spontaneously?
DG, DH, and DS are all positive
DG, DH, and DS are all positive

5. Which statement is FALSE?
DS increases as pressure decreases
for an ideal gas, enthalpy is not pressure-dependent
the lowest value of free energy occurs at equilibrium
DS increases as volume increases
all statements are true
