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

question 17

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, none of the above predictions can be confidently made without further information or calculations.
