Explanation / Answer

Ans 1

Lower the volume of the gas, greater would be the entropy

Higher the atoms in a gas, greater would be the entropy

Higher the temperature of the gas, greater would be the entropy

In liquid state, molecules are arranged in an orderly manner. Therefore in liquid state entropy is least.

Part a

Greatest entropy to least entropy

1 mol CCl4 (carbon tetrachloride) gas at 273K and 40L

Because it has 5 atoms.
1 mol Cl2 gas at 273K and 40L

Because it has 2 atoms.
1 mol radon gas at 273K and 40L

Because it has 1 atoms
1 mol radon gas at 273K and 20L

Because it has 1 mol
1/2 mol radon gas at 273K and 20L

Because it has 1/2 mol
1/2 mol radon gas at 100K and 20L

Because it has less temperature
1/2 mol of liquid radon at 100K

Because it is in liquid state. ( least entropy)
