Question 1

At constant pressure and temperature, which statement is true?
◦ All reactions for which ΔS < 0 are spontaneous.
◦ All reactions for which ΔG < 0 are spontaneous.
◦ All reactions for which ΔH < 0 are spontaneous.
◦ All reactions for which K < 1 are spontaneous.

Question 2

Why is the sign of ΔG rather than the sign of ΔStotal generally used to determine the spontaneity of a chemical reaction?
◦ Free energy is easier to understand than entropy.
◦ ΔG involves thermodynamic functions of the system only.
◦ ΔG can be used for processes that occur under any conditions.
◦ Entropy is based on probability and is therefore less reliable.
