Multiple Choice
You are given pure samples of ethane, C2H6(g) , and toluene, C7H8(l) . What prediction would you make concerning their standard molar entropies at 298 K?
A) S° ethane > S° toluene
B) S° ethane < S° toluene
C) S° ethane ≈ ( S° toluene) ÷ 3
D) S° ethane ≈ S° toluene
E) Since toluene is much more complex than ethane, but ethane is in the gas phase while toluene is a liquid, any of these predictions can be confidently made without further information or calculations.
