In an oxidation half reaction where electrons are LOST, on what side of
the reaction will the electrons be on? Please explain why if you get your answer.

1)The right side with the products
hemistry
ex: Na -> Na+ + e

2)The left side with the reactants
ex: Na+ + e -> Na

The velocity would be 2 

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.

The first one is the one that violate the law
