Diamond and graphite are two crystalline forms of carbon At 1 atm and 25°C, diamond changes to graphite so slowly that the enthalpy change of the process must be obtained indirectly. Determine deltaH(rxn) for: C(diamond) > C(graphite) using the following list: 1) C(diamond) + O2(g) > CO2(g) detlaH = -395.4 kJ 2) 2CO2(g) > 2CO(g) + O2 (g) deltaH = 566.0 kJ 3) C(graphite) + O2(g) > CO2 (g) deltaH = -393.5kJ 4) 2CO(g) > C(graphite) + CO2(g) deltaH = -172.5 kJ delta H overall = _____ kJ
