Final answer:
The provided data do not include the necessary information to calculate the equilibrium constant K for the given reaction.
Step-by-step explanation:
To calculate the equilibrium constant K at 25.0°C for the reaction C(s) + 2Cl2(g) → CCl4(g), we need the thermodynamic data specific to this reaction. Unfortunately, the provided data do not include the necessary information for this particular reaction. Therefore, we cannot calculate the equilibrium constant K for this reaction using the given data.
