Standard Reduction Potential Flashcards
1
Q
What is cell potential?
A
The difference in electric potential energy between the two half-cells
2
Q
What are potentials measured in?
A
- Volts
- 1V=1J/Coulomb
3
Q
What is a standard cell?
A
A galvanic cell in which the entities of the half-cell reactions are at SATP and the solutions have a concentration of 1.0M
4
Q
What is standard cell potential?
A
The electrical potential difference of a galvanic cell that is operating under standard conditions
5
Q
What does a more positive E° indicate?
A
Easier reduction
6
Q
What does a more negative E° indicate?
A
Easier oxidation (for the reverse reaction)
7
Q
When does a spontaneous reaction occur?
A
- DeltaE°r (cell) is >0
- Galvanic or voltaic cell
8
Q
When is the reaction at equilibrium?
A
DeltaE°r (cell) = 0
9
Q
When does a non-spontaneous reaction occur?
A
- DeltaE°r (cell) <0
- Electrolytic cell
