Entropy

Spontaneity is favored by

an increase in entropy (S)

Mixtures

________ tend to have greater entropy than pure compounds.

Substances containing a larger number of atoms generally have

greater entropy than those with fewer atoms.

Microstate

________: a specific configuration of the locations and energies of the particles in a system.

number of particles

The type and ________ that make up the substance.

Temperature

________ is proportional to the average kinetic energy of the particles.

Entropy

a measure of the randomness of a system

Microstate

a specific configuration of the locations and energies of the particles in a system

The most probable distribution has

the largest number of microstates and the greatest entropy

The most probable state will be the one in which

the particles are divided evenly throughout the container.

Gases

have higher entropy than liquids, and liquids higher than solids (neglecting other variables).

With higher temperature,

the particles have greater freedom to move around.

Dissolving a solid in a liquid almost always leads to

an increase in entropy.
