Consider the following cell reaction at 25°C. 2 Cr 3 + ( a q ) + 3 Zn ( s ) → 3 Zn 2 − ( a q ) + 2 Cr ( s ) Calculate the standard cell potential of this cell from the standard electrode potentials, and from this obtain Δ G ° for the cell reaction. Use data in Appendix C to calculate Δ H °; note that Cr(H 2 O) 6 3+ ( aq ) equals Cr 3+ ( aq ). Use these values of Δ H ° and Δ G ° to obtain Δ S ° for the cell reaction.
