2 cards from this section. Quick, good the night before a test.
What is the standard potential of the Reference Hydrogen Electrode?
This is how the electrode is defined.
In the formula E°cell = E°(cathode) - E°(anode), which potential must be larger for a spontaneous reaction?
Think about where reduction occurs.
What does a higher standard electrode potential indicate?
Think about what it means for reduction.
True or False: The standard hydrogen electrode has a potential of 1 V.
Remember how the SHE is defined.
Calculate the overall standard cell potential if given two half-reaction potentials, E°(A) = 0.40 V and E°(B) = -0.50 V. Identify each as anode or cathode.
Remember, the cell potential combines the cathode's reduction potential minus the anode's oxidation.
Discuss what a negative ΔG° suggests for a reaction's E°cell when given a scenario where the Gibbs free energy is measured at 100 kJ.
Connect ΔG and E°cell through their relationship.
