Question 1
Calculate E°_cell for a galvanic cell where the half-reactions are: Cr³⁺ + 3e⁻ → Cr(s) (E° = -0.74 V) and Ag⁺ + e⁻ → Ag(s) (E° = +0.80 V).
💡 Hint: Identify which is the cathode and anode first.
Question 2
Discuss how E°_cell would change if the temperature was increased significantly. What effects would it have?
💡 Hint: Consider how temperature can influence chemical reactions and cell efficiency.
