N2(g)+3h2(g)-> 2nh3(g) δh< 0nh3 was synthesized at 200° c in the presence of a powdered os(s) catalyst, leading to the equilibrium system represented above. which of the following changes would result in more nh3(g) in the mixture after equilibrium is reestablished?

The answer is c fish

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.
