Question 30

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.
