You Are Given Pure Samples of Ethane, C₂H₆(g), and Toluene $\degree$

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 $\degree$ _ethane > S $\degree$ _toluene
B) S $\degree$ _ethane < S $\degree$ _toluene
C) S $\degree$ _ethane $\approx$ (S $\degree$ _toluene) / 3
D) S $\degree$ _ethane $\approx$ S $\degree$ _toluene
E) Since toluene is much more complex than ethane, but ethane is in the gas phase while toluene is a liquid, none of these predictions can be confidently made without further information or calculations.
