You Are Given Pure Samples of Ethane,C₂H₆(g),and Toluene,C₇H₈(l) $\approx$ (S°_toluene) $\div$ 3
D)S°_ethane

question 33

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 \(\approx\) (S°_toluene) \(\div\) 3
• D)S°_ethane \(\approx\) 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 these predictions can be confidently made without further information or calculations.
