The standard state Gibba free energies of formations of C("graphite") and ("diamond") at ``T =298k are `DeltafG^(@) [ C("graphite") = " O "kJ mol^(-1)``DeltafG^(@) [ C("graphite") = " O "kJ mol6^(-1)` The standed state means that the presses should be 1 bar, and substance of graphite [C(graphite)] to diamond [C(diamond )] reduces its volume by `2xx 10^(10) m^(-1)` If C(graphite) is converted to C(diamond ) isothemally at T= 298k the pressure at which C( graphite) is in equilibrium with C(diamond) ,is [ useful infromation : `1 J - Kgm^(2) s^(-2) ` ` 1pa = 1kg m^(-1) s^(-2) : 1^(-) = 10 ^(5) pa]`A. 58001 barB. 1450 barC. 14501 barD. 29001 |
