Journal Entry:

What are some way to increase entropy of a system?

Learning Intentions

• We and relative magnitude of the entropy change associated with chemical or physical processes.

• We will learn how to predict whether or not a physical or chemical process is thermodynamically favored by determination of the signs of both ΔH and ΔS.

• We will learn how to calculate the change in entropy for a reaction using given standard entropies for the reactants and products.

Closing Task:

You can determine sign of entropy for a process and calculate the entropy of a reaction.

Content Standards being covered:

Entropy is a measure of the dispersal of matter and energy. (E.K. 5.E.1) 

Some physical or chemical processes involve both a decrease in the internal energy of the components under consideration and an increase in the entropy of those components. These processes are necessarily "thermodynamically favored".(E.K. 5.E.2)
