Determine the heat of transformaiton of `C_(("dimamond"))rarrC_(("graphite"))` form the following data:
i. `C_(("diamond"))+O_(2)(g) rarr CO_(2)(g), DeltaH^(Theta) =- 94.5 kcal`
ii. `C_(("graphite")) +O_(2)(g) rarr CO_(2)(g),DeltaH^(Theta) =- 94.0 kcal`

Text Solution

Verified by Experts

Substracting equation (ii) from equation (i), the required equation is obtained.
`C_(("diamone")) rarr C(g)`
`Delta_("trans")H^(Theta) =- 94.5-(-94.0) =- 94.5 + 94.0`
`=- 0.5 kcal`
