(a) How many moles of electrons are transferred for each mole of O, that reacts? Justify your answer in terms of the balanced equation and the change in oxidation number of oxygen.
(b) Calculate the electrochemical potential of the overall reaction.
(c) Calculate the value of AGº for the overall reaction.
(d) When the concentration of NADH increases while the concentration of NAD* decreases, will the
electrochemical potential increase, decrease, or remain the same? Justify your answer.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
