Chemistry Que regarding half reactions. (Picture )

The table here shows the standard reduction potentais staedlard reduction potentials of several half-reactions: Half-Reactions(V A"+ + 2e + A 1.46 B2 + 2e,-2B- 0.33 (a) Which is the strongest oxidizing agent (a) Which is the str rongest oxidizing agent (that substance itself reduced) and which is the strongest reducing agent (that substance inself oxidizedy? (b) Which substances can be oxidized by B (c) Which substances can be reduced by B7 uation for a cell that delivers a voltage of 2.59 V under standard-state conditions. (d) Write the overall equationm for a cell that delivers a v

Explanation / Answer

a. C+3 is the strong oxidizing agent

A+2 is strong reducing agent.

b. C+3 can be oxidized by B2

c.

d. 3A --------> 3A+2 + 6e-     E0 = 1.46V

   2C+3 +6e- -------> 2C       E0 =1.13V

---------------------------------------------------------

3A + 2C+3 ----------> 3A+2 + 2C E0Cell = 2.59V
