The chemical reaction for a zinc-oxygen cell is:

Zn_(c) + 1/2O_2(g) + H₂O_(l) = Zn(OH)_{2 (c)}

and the thermodynamic properties at 25 ^oC yield:

DH^o = -357.42 kJ/mol; DG^o = -317.94 kJ/mol

a) Calculate the reversible emf of the cell and its temperature coefficient;

b) Determine the amount of heat to be supplied or removed from the cell to maintain a constant temperature of 25 ^oC under reversible conditions;

c) Calculate the cooling rate necessary to maintain a constant temperature of 25 ^oC when the cell delivers a current of 1 ampere under 1 volt.
