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

### Step 1: Write down the enthalpies of combustion
- The enthalpy of combustion of diamond (ΔH_combustion, diamond) = -395.4 kJ
- The enthalpy of combustion of graphite (ΔH_combustion, graphite) = -393.5 kJ

### Step 2: Understand the relationship
The enthalpy change for the transformation from diamond to graphite can be calculated using the following relationship:
