Graphite to diamond entropy
WebCorrect option is C) Carbon in graphite is sp 2 hybridized i.e. has 33% s character, Thus the C−C bond is more strong in graphite than in diamond, i.e. during combustion less heat is released from graphite and hence enthalpy of graphite is lower. Diamond is crystalline solid which is highly ordered structure while such arrangements are not ...

WebDec 19, 2024 · So, I’m familiar the free-energy argument, but as my book is specifically asking to mention entropy, that is what I’m trying to do. As we’re talking about pressure, I’m guessing the answer would lie in the fact that the volume of diamond is smaller than that of graphite. It would seem then that, due to the high pressure, the increase in ... WebO graphite diamond They have the same entropy. Which compound at 25°C has the least entropy?
