In this PLE we are going to continue discussion of spontaneity, free energy and entropy. (NOTE: If you can not answer a question below enter CNA.)

Important do not press the enter key or the Return key while you are answering these questions. Your Browser will interpret either key the same as clicking the mouse on the Submit button. So BE CAREFUL!

Give me some responses to the questions below and I'll give you some extra credit.

SID#:

Laboratory Section:

1. Briefly explain what the term free energy means to you.

2. What does a negative value for the free energy of a reaction suggest?

3. What does a positive value for the free energy for a reaction suggest?

4. Indicate the sign for S for H in the equation G = H - TS that a reaction must have for a spontaneous reaction.

5. Indicate the sign for S for H in the equation G = H - TS that a reaction must have for a nonspontaneous reaction.

6. Indicate the sign for S for H in the equation G = H - TS that a reaction must have for the spontaneity to be dependent on the relative values of S for H.

7. When a reaction is at equilibrium what do you think the value of G is? Can you explain why?

8. Is there anything about the questions that you feel you do not understand? List your concerns/questions.
