Assignment Help Chemistry
Reference no: EM13292595

The chemical reaction for a zinc-oxygen cell is:

Zn (c) + 1/2O2(g) + H2O (l) = Zn(OH)2 (c)

and the thermodynamic properties at 25 oC yield:

DHo = -357.42 kJ/mol; DGo = -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.
