Which substance in the following pair would have the greater entropy?

Which substance in the following pair would have the greater entropy?

1 molBr2 (l, 1 atm, 8 ?C)

1 molBr2 (s, 1 atm, -8 ?C)

Part D

Which substance in the following pair would have the greater entropy?

Which substance in the following pair would have the greater entropy?

0.312 mol SO2 (g, 0.110 atm, 32.5 ?C)

0.284 mol O2 (g, 15.0 atm, 22.3 ?C)

Explanation / Answer

Part A

The H2O (g) has greater entropy than H2O (l), because the gases has greater entropy than the liquids.

Part B

50 g (0.89 moles) Fe has greater entropy than 0.80 moles Fe, because it has more substances.

Part C

1 mol Br (l) has greater entropy than 1 mol Br(s), because the liquids has greater entropy than the solids.

Part D

0.312 mol SO2 has greater entropy than 0.284 mol O2.
