How do you determine whether a reaction is spontaneous or non spontaneous?
The first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.
What happens when a system in equilibrium is subjected to change?
equilibrium readjusts itself and a new equilibrium is established
Hat will happen when a reactant is added to a system at equilibrium?
The concentrations of reactants and products are modified.
How does a system respond to change once it has reached equilibrium?
At equilibrium its not changing (any more).
What is special about the entropy in thermodynamic equilibrium compared to all statesof a system?
In thermal equilibrium, and only in thermal equilibrium, entropy is constant.
What does it mean to say a system delta g has an equal to zero?
When ΔG is zero, the process is already in equilibrium, with no net change taking place over time
Is Delta S is the change in enthalpy a measure of randomness?
No, delta s is the change in entropy. Delta H is the change in enthalpy, the amount of heat used in a system. Entropy and enthalpy are different, but closely related.

How is delta g related to K?
K brings a process including delta g into equilibrium in a reaction. The two work together to maintain a reaction's equilibrium keeping it stable and helping it to continue at a stable rate.
What does delta S 0 mean in a reaction?
The system becomes more random.
What does the delta s 0 mean in a reaction?
The system becomes more random.
What is the Medical term meaning equilibrium of a system?
Homeostasis means equilibrium of a system.
What effect does a catalyst have on a system equilibrium?
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
What does Le chateliers principal say about upsetting system at equilibrium?
A system of whose equilibrium has been upset will shift to restore equilibrium.
Why do you think the water in the delta is saltier in the fall than in the spring?
During the spring, melt and run off push the equilibrium line further out to sea. During the fall the equilibrium level approaches normal making delta water saltier.
What happens when reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.
What does Le chateliers principles say about upsetting a system at equilibrium?
Le Chatelier's principle says that if a system in chemical equilibrium is disturbed, the system will move in such a way as to nullify that change.
