Question: a) Calculate the cell potential, E cell , for a galvanic cell that use the following cell reaction at 25.0 o C: 3Fe 2+ (aq)

a) Calculate the cell potential, E_cell, for a galvanic cell that use the following cell reaction at 25.0 ^oC:

3Fe²⁺(aq) + 2Cr(s) → 3Fe(s) + 3Fe(s) + 2Cr³⁺(aq)
when the molar concentrations are 0.0200 M for Fe²⁺ ions and 0.00010 M for Cr³⁺ ions.

b) Decide whether the cell potential, E_cell, of the cell in Problem (a), becomes less positive, more positive, or unaffected when the volume in the cathode compartment is decreased.
