The greater molar entropy Δ S for the given substances has to be predicted and reason should be explained. Concept introduction: Entropy Δ S is a thermodynamic quantity, which is the measure of randomness in a system. The term entropy is useful in explaining the spontaneity of a process. For all spontaneous process in an isolated system there will be an increase in entropy. Entropy is represented by the letter ‘S’. It is a state function. The change in entropy gives information about the magnitude and direction of a process. Factors like temperature, molar mass, molecular complexity and phase transition occurring in a reaction influences the entropy in a system. ΔS denatuaration = ΔΗ denaturation T melting
