The substance with lower entropy from LiBr a q and NaBr a q needs to be identified. Concept Introduction : Entropy of any substance is defined by its degree of randomness. It increases with the molecular weight of a substance and its complexity. If concentration and pressure increase, the entropy of the substance decreases. Also, it depends on the state of the substance, for example, solid substances have less entropy as compared to liquid and gaseous substances have maximum entropy. For substances in the same state, a substance with higher molecular weight has greater entropy.
