Final answer:
The given equation is missing the standard entropy values, so we cannot calculate the exact value of ΔS°.
Step-by-step explanation:
To calculate the change in standard entropy (ΔS°) for the reaction C(graphite) + 2Cl₂(g) → CCl₄(l), we need the standard entropy values of the reactants and products. Unfortunately, the given equation is missing the standard entropy values, so we cannot calculate the exact value of ΔS°
