For the cell:
Tl | Tl⁺ (0.001 M) || Cu²⁺ (0.1 M) | Cu
at 298 K. The cell potential can be increased by
Options:(select one or more)
Answer:
A, D
Solution:
Cell: Tl | Tl⁺ (0.001 M) || Cu²⁺ (0.1 M) | Cu
According to the Nernst equation, cell potential increases when the concentration of reactants increases or the concentration of products decreases.
Thus, increasing [Cu²⁺] or decreasing [Tl⁺] increases Ecell.
