The sign of ΔH for the formation of diamond from graphite... | Filo

Calculate ΔG^∘ for the process C( diamond ) ⟶C( graphite ) Is the formation of graphite from diamond favored at 25^∘ C ? If so, why is it that diamonds do not become graphite on standing? | Numerade

The standard state Gibbs energies of formation of C_{(graphite)} and C_{(diamond)} T = 298 K areDelta_{f}G^{circ}C_{(graphite)} = 0kJ mol^{-1}Delta_{f}G^{circ}C_{(diamond) }= 2.9 kJ mol^{-1}The standard state means that the pressure should be 1 bar, and substance should be pure a given temperature. The conversion of graphite C_{(graphite)} to diamond C_{(diamond)} reduces its volume by 2times 10^{-6} m^{3} mol^{-1}. If C_{(graphite)} is converted to C_{(diamond)} isothermally T = 298 K, the pres
