Explanation / Answer

1)

reducing agent should get oxidised

So, Li+ and Ag+ are already oxidised form

So, they can’t be true

From data table

Eo((Ag+/Ag(s))) = 0.7996

Eo((Zn2+/Zn(s))) = -0.7618

Eo((Al3+/Al(s))) = -1.662

The one with greater Eo value of reduction will be reduced easily

So, it will be better oxidising agent and weaker reducing agent

Thus, Eo is direct inverse measure of Reducing power

Decreasing order of Reducing Power is:

Al(s)

Zn(s)

Ag(s)
