If 20.00 mol of hydrogen gas completely reacted with 20.00 mol of chlorine gas
at constant pressure, releasing 3700 kJ of heat, which of the following
thermochemical equations is correct?
H2(g) + Cl2(g) => 2HCl (g); AH° = -185 kJ
H2(8) + Cl2(8) => 2HCl (g); AH° = +185 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = +370 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = -3700 kJ
H2(g) + Cl2(g) => 2HCl (g); AH° = -1850 kJ

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.

We can't until we know what we are working with or on
