At 500 kbar pressure density of diamond and graphite are 3 "g"//"cc" and 2 "g"//"cc" respectively, at certain temperature T. Find the value of |DeltaH-DeltaU| ("in kJ"//"mole") for the conversion of 1 mole of graphite 1 mole of diamond at 500 kbar pressure. (Given : 1 "bar" = 10^(5) "N"//"m"^(2))

PASSAGE-I : Diamond and graphite are two allotropic forms of carbon which are crystalline in nature. They differ physically but chemically they are similar. Diamond is the hardest crystalline form of carbon. In diamond each carbon atom is linked to four other carbon atoms by covalent bonds. In graphite, each carbon atom is linked to three other carbon atoms by covalent bond. Graphite is relatively soft and greasy. It is a good conductor or electricity. Which allotrope gives carbon dioxide on heating?

    Allotropes of carbon: There are three forms of carbon. i.e., diamond, graphite and fullerene which exxist in crystalline form. Graphite and diamond occur in nature. The structure of diamond is tetrahedral with sp^(3) hybridisation and diamond exist in 3-D netowrk solid. in graphite, carbon is sp^(2) hybridised. each carbon linked to other carbon linked to other carbon atom forms hexagonal ring. it has a layered structure. diamond and graphite are purest form of carbon. Fullerene constitute a new family of carbon allotropes. Consisting of large spheroidal molecule of compound with general formula C_(2n) . common fullerene C_(6),C_(70) , contain 5 and 6 membered rings. Q. The inter layer distance in graphite is
