Question

explain in terms of entropy which one would show higher entropy crystalline or amorphous solids

Answer 1

Answer:

Crystalline solids have regular ordered arrays of components held together by uniform intermolecular forces, whereas the components of amorphous solids are not arranged in regular arrays.

Answer 2

Answer:

According to the second law of thermodynamics, the entropy of the universe, S

universe

must always increase for a spontaneous process, that is, S.universe >0. The Concept of Entropy— entropy, S, is a measure of the energy distribution within a system. Entropy changes, ΔS are associated with changes in the way in which a system’s energy is distributed among available energy levels. The third law of thermodynamics states that the entropy of a pure, perfect crystal at 0K can be taken to be zero. This serves as a starting point for the experimental determination of standard molar entropies, which can be used to calculate entropy changes in chemical reactions.

The direction of spontaneous change is the direction in which total entropy increases.
