The value of Δ r G ° for the vaporization of mercury at 25 ° C has to be calculated. Concept Introduction: The entropy of a system is the randomness created by the molecules. The order of entropy is gas > liquid > solid . Entropy change of a reaction will be positive when the total number of product molecules is greater than the total number of reactants molecules and entropy change will be negative when total reactants molecules are greater than product molecules.
