Question 1.
What is the equation relating Gibbs Free Energy to cell potential?
Show hintHide hint
Remember the relationship involves spontaneity.
Question 2.
Is a positive cell potential indicative of a spontaneous reaction?
Show hintHide hint
Think about how energy behaves in reactions.
3Question 3.
What does a positive cell potential indicate?
- Nonspontaneous reaction
- Spontaneous reaction
- Requires energy input
Show hintHide hint
Think about energy flow in the reaction.
4Question 4.
True or false: Gibbs Free Energy change (ΔG°) must be negative for a reaction to be spontaneous.
- True
- False
Show hintHide hint
Reflect on what energy changes imply.
Question 5.
A certain electrochemical cell has a cell potential (E°cell) of 0.75 V and transfers 4 electrons. Calculate ΔG° for this system.
Show hintHide hint
Make sure to use the formula correctly for calculations.
Question 6.
Explain how a negative Gibbs free energy affects the capacity of a battery design. What considerations would be crucial in system development?
Show hintHide hint
Think about how energy supply and stability link to design elements.
