# O ENTROPY AND FREE ENERGYCalculating entropy change using the Boltzmann hypothesisDETwo nitro (NO, groups are chemically bonded to a patch of surface. They can't move to another location on the surface, but theycan rotate (see sketch at right).It turns out that the amount of rotational kinetic energy each NO, group can have is required to be a multiple of &, where-24J. In other words, each NO, group could have & of rotational kinetic energy, or 2&, or 3, and so forth -but it=1.0 x 10cannot have just any old amount of rotational kinetic energy.Two rotating NO, groupsSuppose the total rotational kinetic energy in this system is initially known to be 100E. Then, some heat is removed from thebonded to a surface.system, and he total rotational kinetic energy falls to 75&.
