The change that would cause entropy to decrease is CO2 gas changing to solid:
What is entropy?
Entropy refers to the degree of randomness of a substance.
The higher the degree of randomness the higher the entropy value of that substance.
Entropy increases with increase in temperature as particles of substances gain more kinetic energy.
However, lowering temperature decreases entropy values.
The change from gas to liquid or solid involves lowering of temperature.
Therefore, the change that would cause entropy to decrease is CO2 gas changing to solid.
