Determine the heat of transformation of ...

Determine the heat of transformation of C(diamond) `to` C(graphite) from the following data.
C(graphite) `+O_(2)to CO_(2)(g), " " Delta H=-94.9` k cal

Text Solution

Verified by Experts

Subtracting equation (ii) from (i), the required equation is obtained, therefore ,
C(diamond) `to` C(graphite), `Delta_("trans")H=-94.5-(-94.0)=-0.5` k cal
