9) a) Calculate the enthalpy change for the conversion of diamond to graphite: Cdiamond (5)→→ Cgraphite (s) From the information provided: Cgraphite (s) + O2 (g) Cdiamond (s) O₂ (g) C → → CO₂ (g) CO₂ (g) b) Is the conversion of diamond to graphite spontaneous? ΔΗΞ -394 kJ ΔΗ = -396 kJ 10) Use the standard heat of formation listed in Table 8.2 to calculate the standard enthalpy change for the following overall reaction: 4 NH3(g) 7 O2 (g)→ 4NO₂ (g) + 6 H₂O (1) AH(NO₂) = 34 kJ/mol
12) At what temperature is the following process spontaneous at 1 atm? Br2 (1)→ Br2 (g) AH = 21.0 kJ/mol, and AS°= 93 J/K mol
