The entropy change in the conversion of a solid into its different states can be obtained by using
Options
(a) The third law of thermodynamics
(b) Equation ΔS = ₀∫ Cp/T dt
(c) Equation ΔS = ΔHf/Tf
(d) Equation ΔG = ΔH – TΔS
Correct Answer:
The third law of thermodynamics
Explanation:
Third law of thermodynamics has been utilised in calculating absolute entropies of solids, liquids and gases at different temperature and also in evaluating entropy changes of chemical reaction and other processes.
