The substance between Ga ( s ) and Ga ( l ) which has greater standard molar entropy at 25 ° C temperature has to be predicted. The reason for the corresponding answer has to be stated. Concept Introduction: The term entropy is used to represent the randomness in a system. When a system moves from an ordered arrangement to a less order arrangement, then the entropy of the system increases. The second law of thermodynamics state that “the entropy of the system either increases or remains the same.”
