Data: $\Delta$ H_f $\degree$ (diamond) = 1.895 kJ/mol; S $\degree$ (diamond) = 2.337 J mol¯¹ K¯¹; S $\degree$ (graphite) = 5.740 J mol¯¹K¯¹.

• A) (\(\Delta\)G\(\degree\) = 2.19 kJ; forever
• B) (\(\Delta\)G\(\degree\)= -1.90 kJ; not forever)
• C) (\(\Delta\)G\(\degree\) = -2.90 kJ; not forever)
• D)( \(\Delta\)G\(\degree\) = 1.90 kJ; forever)
• E) (\(\Delta\)G\(\degree\) = < -1000 kJ; not forever)
