Three of the forms of elemental carbon are graphite, diamond, and buckminsterfullerene. The entropies at 298 K for graphite and diamond are listed in Appendix C.
(a) Account for the difference in the S° values of graphite and diamond in light of their structures (Figure 12.30).
(b) What would you expect for the S° value of buckminsterfullerene (Figure 12.47) relative to the values for graphite and diamond? Explain.
