Pressure induced transition of graphite to diamond -- homework help
Process is being carried out at 25*C and requires an increase in pressure until he graphite and diamond are in equilibrium. The following data is given at 25*C
dG(25*C, 1atm) = gdiamond - ggraphite = 2866 J/mol
density diamond = 3.51 g/cm^3
density graphite = 2.26 g/cm^3
Estimate the pressure at which these two forms of carbon are in equilibrium at 25*C.
This is a homework question for my thermo II class, I have been looking at it for a day or so now and can't come up with a solution. Based on the densities it's clear it will take a lot of pressure for the transition. Any help would be greatly appreciated, it's been 6 months since thermo I so I am a little rusty! Thanks again!
