Let’s say a climate accord is reached between different countries. each wealthy country agrees that starting in 2020 they will gradually lower carbon emissions until they are 80% lower by 2060. this would require cuts in emissions of about 4% per year. 1. how much would carbon prices have to rise each year? 2. how much higher would carbon prices be by 2060? 3. how much would a gallon of gas cost in 2060 (in today’s % increase in energy prices resulted, on average, in a 2.1% decline in the quantity consumed in the short run and a 6.1% decline in the long run.)

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.
