Question

Part A:Rank these systems in order of decreasing entropy.

Part B:Classify each process by its individual effect on the entropy of the universe, S.

If you could explain how you got the answer it would be really helpful!

Thank you in advanced:)

Part A Rank these systems in order of decreasing entropy. Rank from highest to lowest entropy. To rank items as equivalent, overlap them. 1 mol of 1/2 mol of 1 mol of 1 mol of 1/2 mol of chlorine gas at liquid argon carbon tetrafluoride gas at argon gas at argon gas at 273 K and 40 L 273 K and 40 L at 100 K 100 K and 20 L 273 K and 20 L Greatest entropy The correct ranking cannot be determined. Reset Help 1 mol of 1/2 mol of argon gas at argon gas at 273 K and 40 L 273 K and 200 L Least entropy

Explanation / Answer

Answer:

Entropy means Increasing the disorderness.

PART A:

1 mol Ar gas at 273 K in 40L > 1 mol of Chlorine gas at 273 K in 40 L. > 1 mol carbon tetrachloride at 273 K in 40 L > 1/2 mol of Ar at 273 in 20L > 1 mol of Ar at 273 in 20 L > 1/2 mol of Ar gas at 100K in 20 L > 1/2 mol of liquid Ar at 100 K.

PART B:

Increase thr S of the Universe:

A process run infinitesmally slowly at equilibrium and reverse to its original state.

Motion of Friction less pendulum.

Melting of Ice cream from solid to liquid at 25 C

Hydrogen peroxide slowly decomposition in to water and Oxygen.

Does not affect S of the universe:

A constant composition mixture of solid and liquid water at STP ( 273.15 K and 1atm).

Decrease S of Universe:

Titration of Sodium hydroxide and HCl
