If the reduction potential is positive it is voluntarily in the direction written. If the reduction potential was an unfavorable the turning back reaction would certainly be spontaneous.

Thanks because that the quick reply, yet I'm quiet a bit confused. So, for instance, the palliation potential because that the first half reaction, together I created it, is –0.54v, so does that make the totality equation spontaneous? i am really confused
might you please sophisticated a small further? We simply learned this principle a couple days back and I'm still no comfortable with the material.Thanks again,Lucas

Remember that reduction is a gain in electron (OILRIG - oxidation is loss/reduction is gain).So palliation potentials are for the reaction in the reduction direction, if you turning back the reaction (like friend did with iodine) it i do not care an oxidation reaction.The reaction v the greater more optimistic reduction potential will continue spontaneously in the reduction direction as soon as reacted with another compound v a smaller reduction potential (in which instance it will proceed in the oxidation direction).
