`C("diamond")toC("Graphite")`, `DeltaH=-ve`. Then shows that

C(Diamond ) to C(Graphite), DeltaH =-ve, this indicates that _____

C ("diamond") rarr C ("graphite") , DeltaH = -ve , this indicates that

For the change, C_("diamond") to C_("graphite"), DeltaH = -1.89 kJ , if 6g of diamond and 6g of graphite are separately burnt to yield CO_2 , the heat liberated in first case is

For the transition C_("(diamond)") rarr C_("(graphite)"), DeltaH=-1.5 kJ . It follows that

For the transition C_("(diamond)") rarr C_("(graphite)"), DeltaH=-1.5 kJ . It follows that
