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

question 78

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.
