Question 1

Entropy is a measure of
◦ free energy.
◦ molecular randomness.
◦ the heat of a reaction.
◦ the rate of a reaction.

Question 2

Without doing any calculations, determine whether the standard entropy change, ΔS° is positive or negative for each of the following reactions.

reaction 1: C(graphite) + O2(g) → CO2(g)
reaction 2: 2 CO(g) + O2(g) → 2 CO2(g)

◦ ΔS° is positive for reaction 1 but negative for reaction 2.
◦ ΔS° is positive for both reactions.
◦ ΔS° is negative for both reactions.
◦ ΔS° is positive for reaction 2 but negative for reaction 1.
