Compare the standard molar entropy for three common forms of iodine in different states ofmatter. Explain the trend in the values; why are they different?

S

Expert Solution

Standard molar entropy is the amount of entropy need it of 1 mole of a substance standard conditions 1atm and 298K, because this is an extensive state function this depends on the amount of total substance that we have. We can determine the entropy qualitative taking a few considerations:

The entropy of gas is bigger than liquids and solids. Because we have less restriction between the atoms so we have more disorder in gas than liquids and solid. This is why the S is bigger in I(gas) and I2(gas) than in I2(solid).
The entropy of gases is bigger in the gas that has the lighter molecular weights, because has more liberty in the molecule.
The entropy of gases with similar molecular weights, its going to be bigger in the gas that has a bigger amount of atoms in its structure.
The entropy is going to be bigger as more weak is the bond between the atoms of a molecule, in this case we have that I2 has a weaker bond tramolecular that
