Question 1

What is the correct expression for standard cell potential?

  • E°cell = E°(anode) - E°(cathode)
  • E°cell = E°(cathode) - E°(anode)
  • E°cell = E°(cathode) + E°(anode)

💡 Hint: Remember the role of anode vs. cathode.

Question 2

Which condition leads to a negative Gibbs Free Energy (ΔG)?

  • True
  • False

💡 Hint: Think about the relationship between Gibbs Free Energy and spontaneous reactions.

Challenge Problems

Push your limits with challenges.

Question 1

A galvanic cell consists of a Zn/Zn^2+ half-cell and a Ag/Ag^+ half-cell. The standard reduction potentials are Zn^2+ + 2 e− → Zn(s) (E° = -0.76 V) and Ag+ + e− → Ag (E° = +0.80 V). Calculate the standard cell potential and discuss the spontaneity.

💡 Hint: Identify which half-reaction has the higher potential.

Question 2

For a concentration cell formed with a salt solution containing different ion concentrations, calculate the cell potential using given concentrations and apply the Nernst equation.

💡 Hint: Make sure to establish concentrations and n value correctly before calculation.
