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
