T. will diamond graphite, and liquid carbon all exist in equilibrium? 10 A triple point is a tempera pressure at which three phe coexist in equilibrium. 10 10 4300 atm Pha 10 10 Using the phase diagram locate the triple point wher exists as diamond, graphite liquid. Then, read the x-an values for that point to dete values of P and T. 100000 K 10 T- 1 Which solid form of carbon is more dense? Remember that more dense are usually more stable at higher pressures diamond O graphite OR e

Answer 1

Carbon Phase Diagram 106 solid (diamond) 105 liquid 104 P 103 (atm) 102 solid II (graphite) gas 10- 1 0 1000 2000 4000 5000 6000 3000 T(K)

The triple point of Graphite,Diamond and liquid carbon is around 4000 to 4200 K and a pressure of around 125 to 130 kbar.
