You are given pure samples of pentane, CH3CH2CH2CH2CH3(l) , and 1,3-pentadiene, CH2=CHCH=CHCH3(l) . What prediction would you make concerning their standard molar entropies at 298 K?
A) S°pentane > S°1, 3-pentadiene
B) S°pentane < S°1, 3-pentadiene
C) S°pentane ≈ S°1, 3-pentadiene
D) S°pentane = S°1, 3-pentadiene + 2 S°H2
E) More information is needed to make reasonable predictions.
