8) C(diamond) → C(graphite)
delta G° = -2.9 kJ/molrxn
Which of the following best explains why the reaction represented above is not observed to occur at
room temperature?
(A) The rate of the reaction is extremely slow because of the relatively small value of AGº for
the reaction.
(B) The entropy of the system decreases because the carbon atoms in graphite are less ordered
than those in diamond.
(C) The reaction has an extremely large activation energy due to strong three-dimensional
bonding among carbon atoms in diamond.
(D) The reaction does not occur because it is not thermodynamically favorable.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
