The heat of combustion of graphite at 298 K is -393.795 kJ/mole, while that of diamond's combustion at the same temperature is -395.692 kJ/mole. The specific heats for these substances are 720.83 and 505.58 `J kg^(-1)K^(-1)` respectively. Calculate the heat of graphite's transformation into diamond at 273 K.

Explanation

To calculate the heat of transformation of graphite into diamond at 273 K, we will follow these steps:

### Step 1: Write the equation for the transformation
The transformation of graphite (C) into diamond (C) can be represented as:
\[ \text{C (graphite)} \rightarrow \text{C (diamond)} \]

### Step 2: Use the heats of combustion
The heat of combustion at 298 K for graphite is given as:
