For the cell:

Tl | Tl⁺ (0.001 M) || Cu²⁺ (0.1 M) | Cu

$E_{ce ll} = 0.83 V$ 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.
