Consider comparing 1 mole of NH3 at 10 bar and 500 K vs. 1 mole of Ne at 10 bar and 500 K.
Answer the following questions using molecular arguments. Explain your choice with diagrams and descriptions of the interactions involved.

(a) In which case is the compressibility factor, z, higher?

(b) In which case is the entropy, s, higher? You need consider only the “spatial” contribution to entropy.
