15.2 Predict the entropy change for a given reaction or process [HL IB Chemistry]
The entropy of a system approaches a constant value as the temperature approaches absolute zero.

Explaining what entropy is
In statistical mechanics, entropy is an extensive property of a thermodynamic system. It is closely related to the number Ω of microscopic configurations that are consistent with the macroscopic quantities that characterize the system. Under the assumption that each microstate is equally probable, the entropy
is the natural logarithm of the number of microstates, multiplied by the Boltzmann constant kB. Formally,
