answer 11 and 12 explain why you got that answer please. I got them both wrong.

Given the half reactions and reduction potential below on the left, answer the questions on the right. State the specifie substance or ion that answers each question and include the physical state. HALF REACTION E0 (v) F2(g) + 2e- rightarrow 2F-(aq) +2.87V I2(g) + 2e- rightarrow 2I-(aq) +0.53 V Cu2+(aq) + 2e- rightarrow Cu(s) +0.34 V Al3-(aq) + 3e- rightarrow Al(s) -1.66 V What is the best oxidizing agent? What is the worst oxidizing agent? What is the best reducing agent? What is the worst reducing agent? Consider the following reduction potentials: Mg2+(aq) + 2e- rightarrow Mg(s) E0red = -2.37 V V2+(aq) - 2e- rightarrow V(s) E0red = -1.18 V Cu2-(aq) + e- rightarrow Cu+(aq) E0red = +0.15 V Which one of the following reactions will be product-favored? Mg2+(aq) + V(s) rightarrow V2+(aq) + Mg(s) Mg2+(aq) + 2Cu+(aq) rightarrow 2Cu2+(aq) + Mg(s) V2+(aq) + 2Cu2+(aq) V(s) + 2Cu2+(aq) rightarrow V2+(aq) + 2Cu+(aq)

Explanation / Answer

11.Oxidising agent is the one which get reduced easily..The one with the higher reduction potential is the best oxidising agent(F2(g) ) reduced easily.

worst oxidising agent is the one which have lower reduction potential.Al3+

reducing agent is the one which get oxidised easily.

the last reaction having negative reduction potential is the one having greater oxidation potential(if you reverse the sign it become oxidation potential)

the best reducing agent is Al(s)

the worst reducing agent is having lower oxidation potential 2F-

12.The one with negative potential acts as anodic half cell and the one with positive potential acts as cathode .the only positive reaction is,

Cu2+(aq) + e
