Given that `C_("(graphite)") rarr C_((g)), DeltaH=+716.7 kJ`.
`C_("(diamond)") rarr C(g), DeltaH=714.8 kJ`. The `DeltaH` for the following reaction is
`C_("(graphite)") rarr C_("(diamond)")`

C(s)("diamond") rarr C(g), DeltaH =- 714.8 kJ DeltaH is the heat of …………….of diamond.

Which of the following statement is wrong for C_((graph ite))rarr C_((diamon d))?DeltaH^(@)=+1.90kJ

Given that: i. C("graphite") +O_(2)(g) rarr CO_(2)(g), DeltaH =- 393.7 kJ ii. C("diamond") rarr C("graphite"), DeltaH =- 2.1 kJ a. Calculate DeltaH for buring of diamond of CO_(2) . b. Calculate the quantity of graphite that must be burnt to evolve 5000 kJ of heta.

Given that: i. C("graphite") +O_(2)(g) rarr CO_(2)(g), DeltaH =- 393.7 kJ ii. C("diamond") rarr C("graphite"), DeltaH =- 2.1 kJ a. Calculate DeltaH for buring of diamond of CO_(2) . b. Calculate the quantity of graphite that must be burnt to evolve 5000 kJ of heta.

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

1) C_("Graphite") + O_(2(g)) rarr CO_(2(g)) , DeltaH = -94 K.Cals 2) C_("Diamond") + O_(2(g)) rarr CO_(2(g)) , DeltaH =-94.5 K.Cals From the above data the heat of transition of C_("diamond") rarr C_("Graphite")
