1 out of 10 attemp Enter your ans wer in the provided box 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. DetermineA for rxn (diamond)- â C (graphite) C with equations from the following list: (1) Cdia (2) 2CO2(g)â2CO(g ) + O2(g) (3) C(graphite) +02(g)âCO2(g) (4) 2C0(g)âC(graphite) + CO2(g) AH AH-566.0 kJ AH--393.5 kJ AH--172.5kJ =-395.4 kJ (diamond) +02(g) â CO2(g) AH overall = kJ
