Problem Details

Use the following data to determine the Delta H for the conversion of diamond into graphite: 

Cdiamond (s) + O2 (g) → CO2 (g)    ΔH° = -395.4 kJ 

2CO2 (g) → 2CO (g) + O2 (g)     ΔH° = 566.0 kJ 

2CO (g) → Cgraphite (s) + CO2 (g)     ΔH° = -172.5 kJ 

Cdiamond (s) → Cgraphite (s)     ΔH° = ?
