Tired of studying thermodynamics, you decide that you will abandon chemical engineering and get rich quick by manufacturing diamond from graphite.It is known that the difference between the Gibbs free energy for diamond and graphite at normalroom temperatures (25° C) is 2866 J/mol, i.e.,:g (25°C, 1 atm) = gdiamond – ggraphite = 2866 J/molAlso, the density data of diamond and graphite at 25°C are also known as such:diamond = 3.51 g/cm3graphite = 2.26 g/cm3Using this information, estimate the pressure you would have to exert in order to have diamondand graphite be in equilibrium at room temperature.

Question
Tired of studying
It is known that the difference between the Gibbs free energy for diamond and graphite at normal
room temperatures (25° C) is 2866 J/mol, i.e.,:
g (25°C, 1 atm) = gdiamond – ggraphite = 2866 J/mol
Also, the density data of diamond and graphite at 25°C are also known as such:
diamond = 3.51 g/cm3
graphite = 2.26 g/cm3
Using this information, estimate the pressure you would have to exert in order to have diamond
and graphite be in equilibrium at room temperature.
