You Are Given Pure Samples of Ammonia, NH₃(g), and Nitrogen $\degree$

You are given pure samples of ammonia, NH₃(g) , and nitrogen trifluoride, NF₃(g) . What prediction would you make concerning their standard molar entropies at 298 K?

A) S $\degree$ _ammonia > S $\degree$ _{nitrogen trifluoride}
B) S $\degree$ _ammonia < S $\degree$ _{nitrogen trifluoride}
C) S $\degree$ _ammonia $\approx$ S $\degree$ _{nitrogen trifluoride}
D) Other conditions need to be specified before a reliable prediction can be made.
E) Even if more conditions are specified, a reliable prediction cannot be made.
