Gibb's Free Energy of Formation



  Hi CCL'ers
  I am a HyperChem user. As you may know, HyperChem allow the user to calculate
 enthalpies of formation. Can anyone tell me if it possible to calculate
 entropies of formation and therefore Gibb's Free Energy of Formation.
 I'll summarise replies and post them to everyone. Thanks in advance.
