A solid camping fuel has a stated energy content of 50.0 kJ/g. Determine its efficiency if a 2.50 g piece
g
of the fuel was required to increase the temperature
of 500.0 g of soup (c = 3.77 J/g.°C) in a 50.0 g
aluminum pot by 45.0°C.

The answer would be true

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.
