If 12 mole of oxygen are reduced at the end of electron tran

If 1/2 mole of oxygen are reduced at the end of electron transport, how many moles of electrons and protons are needed in order to accomplish that conversion? a. two moles of protons and two moles of electrons   b. two moles of protons and one mole of electrons    c. two moles of protons and four moles of electrons   d. two moles of protons and eight moles of electrons   e. none of the above. Which answer is correct and WHY?

Solution

1/2 O2 +2e ---> O2-

Hence answer is

e.none of the above

as onlu two moles of electrons are required
