Consider the following chemical equation whose delta(G) = 9kcal/mol: AC + BD ---> AB + CD what are the reactants and what are the products is this reaction spontaneous? How do you know? Is energy released or consumed by this reaction? If an enzyme, which catalyzes this reaction is added, what will happen to delta (G) If this reaction is coupled to another reaction, whose delta(G) is -12 kcal/mol, what will be the net delta(G) value? will the overall reaction be spontaneous
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)
