To calculate the equilibrium pressure for the conversion of graphite into diamond at 298 K, we can follow these steps: ### Step 1: Understand the Reaction The conversion of graphite (G) to diamond (D) can be represented as: \[ \text{C (graphite)} \rightleftharpoons \text{C (diamond)} \] ### Step 2: Use the Gibbs Free Energy Equation At equilibrium, the change in Gibbs free energy (\( \Delta G \)) is related to the change in volume (\( \Delta V \)) and pressure (\( P \)) by the equation: ...
