Homework Help: Chemistry

Posted by Katherine on Thursday, March 8, 2012 at 10:42pm.

Under standard conditions (298 K and 1 atm), which statement is true?
a] diamond converts to graphite spontaneously
b] graphite converts to diamond spontaneously
c] none of the above

How can the spontaneity of the reaction be reversed? a] increase the temperature
b] decrease the temperature
c] none of the above

If i calculated it right i got Delta H to be -1.9 kJ/mol
Delta S to be 3.3 J/mol k
and Delta G to be -2.9 kJ/mol
does this mean that the first part was a] diamond converts to graphite spontaneously since delta G was negative?
