A voltaic cell is based on Ag+ (aq) / Ag(s) and Fe3+(aq) / Fe2+ (aq) half-cells. (a)

Question:

A voltaic cell is based on Ag+ (aq) / Ag(s) and Fe3+(aq) / Fe2+ (aq) half-cells.
(a) What is the standard emf of the cell?
(b) Which reaction occurs at the cathode and which at the anode of the cell?
(c) Use S° values in Appendix C and the relationship between cell potential and free-energy change to predict whether the standard cell potential increases or decreases when the temperature is raised above 25°C.
