Question

A Cr(s)|Cr3 (aq)||Fe3 (aq)|Fe(s) galvanic cell has a standard cell potential of 0.700 V. Calculate the Gibbs free energy change at 25 °C when 2.20 g of iron is deposited. Assume the concentrations in the cell remain at the standard state values of 1 M through the entire deposition process.

delta G=? J

Calculate the maximum amount of work done by the cell on its surroundings.

wmax=? J
