Entropy is a measure of randomness. Consequently, systems that are more chaotic have a higher entropy value. If a change makes a system more random, S is positive. If a change makes a system more ordered, S is negative.

For the SAT II Chemistry exam, you’ll be expected to be have an understanding of all of the laws of thermodynamics, so to refresh your memory, the first law of thermodynamics says that energy can neither be created nor destroyed. The second law of thermodynamics says that the disorder of the universe, meaning its entropy,

Entropy change for a reaction ... Even without knowing the actual values for the So of substances, it is possible to predict the sign of Delta So for a reaction or phase change. It is useful to remember that the entropy of a system will increase when:

Whether a reaction ever will proceed by itself depends on two quantities that sometimes co-operate but more often conflict: heat or energy, and disorder or entropy.

In spontaneous reactions there is a tendency for things to become less ordered. This increasing amount of disorder is referred to as Entropy.

Chapter 6: Introduction to Chemistry and Entropy This chapter will introduce chemistry, organic chemistry, quantum mechanics, and thermodynamics. The goal is to make sure that all readers understand how and why chemicals react with each other, and how and why the laws of thermodynamics influence these reactions.
