The enthalpies of combustion of diamond and graphite are - 395.4 kJ and - 393.5 kJ respectively calculate the enthalpy of transformation from diamond to graphite.

Explanation

To find the enthalpy of transformation from diamond to graphite, we can use the enthalpies of combustion provided for both forms of carbon. Here’s a step-by-step solution:

### Step 1: Write the equations for the combustion of diamond and graphite.

1. The combustion of diamond can be represented as:
\[ C_{(diamond)} + O_2 \rightarrow CO_2 \quad \Delta H_{combustion} = -395.4 \, \text{kJ} \]
