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

question 7

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.
