Calculate the maximum work available from 35.0 g of aluminum in the following cell when the cell potential is 1.23 V: Al(s) | Al³+ (aq) || H+ (aq) | O2(g) | Pt Note that O2 is reduced to H2O. Maximum work =

Zinc-air batteries are actively being researched because one reactant (oxygen) is provided in infinite supply for free. The standard cell potential for this battery is 1.65 V. If the cell potential is 1.61 V, what is the partial pressure of oxygen in the cell and a temperature is 25.0\deg C? The reaction in the cell converts Zn(s) and O2(g) into ZnO(s). 2Zn(s) 02 (g) -> 2ZnO(s)
