ΔS = ΔH/T, ΔS(per mole) = ΔH per mole/T = 6000/273 = 21.98 J K⁻1 mol⁻1

1. ΔS = ΔH/T
2. ΔS = ΔH/T × 273
3. ΔS = ΔH/T × 6000
4. ΔS = ΔH/T × 21.98 J K⁻1 mol⁻1

Correct answer: ΔS = ΔH/T

Solution

The correct formula for entropy change is ΔS = ΔH/T, as shown in the question's calculation. The other options incorrectly modify the formula.
