Students fractionating two proteins of unequal molecular weight noted that the proteins eluted from the sec column simultaneously. which of the following statements best explains this observation? (a) the shape of a molecule is unrelated to its rate of migration. (b) one of the proteins has a molecular weight beneath the exclusion limit. (c) the molecular weight of both proteins exceeds the exclusion limit. (d) both proteins possess equal charge at the buffered ph.

Yes i think so not 100 percent sure though

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
