Stable carbon

Postby Samantha Jimenez 4k » Fri Jan 25, 2019 7:57 pm

Could someone explain how graphite is the most stable form of carbon?

Graphite is the most stable form of carbon because it is the most thermodynamically stable. Graphite does not require as much pressure to be formed than like diamond.

It can also be seen in this carbon phase diagram that carbon is in the form of granite at standard conditions

As far as I know, it depends on crystalline structure. Dr. Lavelle mentioned in class that graphite is sp2 hybridized, while diamond (which forms when graphite is subject to high pressure) is sp3 hybridized.
