Which phase has the lowest entropy? Why? How does a change in phase affect entropy changes in a reaction?

ANSWER: Entropy is the measure of the randomness in a structure. This means, entropy, when it is in solid state is at the lowest entropy, this is because the molecules are packed together, like in order, and don’t have the ability to make more collisons. However there is some entropy, depending on patterns of solid, some will have more or less entropy, however not as much as liquid state or gas state.
A change in the phase can affect the entropy changes in a reaction because when you change from a liquid to a gas or more, you are having a change which means the entropy is increased, even when it is turning from liquid state to solid state.

You're welcome :)
