Determining the realtive strengths of oxidizing and reducing agents  a. Arrange the following oxidizing agents in order of increasing strength unde standard-state conditions: `Br_(2)(1), Fe^(3+)(aq.), Cr_(2)O_(7)^(2-)(aq.)` b. Arrange the following reducine agents in order of increasing strength under standard state condition: `Al(a), Na(s), Zn(s)`  Strategy: Pick our the half reactions in Table 3.1 that involve the given oxidizing  or reducing agents and list them, along with their `E^(@)` value increases (i.e. becomes more positive) whereas the strength of a reducing agent increases as the `E^(@)` value decreases (i.e. becomes more negative).
