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

Multiple Choice

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° _ammonia > S° _{nitrogen trifluoride}
B) S° _ammonia < S° _{nitrogen trifluoride}
C) S° _ammonia ≈ S° _{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.
