The standard entropy of a mole of N2O4 is higher than that of a mole of NO2.
Entropy is a gauge of disorder, hence substances having greater molar values might be thought of as being more disorganized. The substance's condition has the most impact on the molar entropy. Compounds that are gases will have a far higher molar entropy than compounds that are liquids or solids because gases are much more widely dispersed. The well-known "products minus reactants" approach, which multiplies the absolute entropy of each reactant and product by its stoichiometric coefficient in the balanced chemical equation, is used to compute S° for a chemical reaction from standard molar entropies.
