Redox Reactions And Electrochemistry Ques 167

Question: Electrode potential data are given below : Fe3+(aq)+eFe1(aq);,Eo=+0.77V Al3+(aq)+3eAl(s);,Eo=1.66V Br2(aq)+2e2Br(aq);,Eo=+1.08,V Based on the data given above, reducing power of Fe2+,,Al and Br will increase in the order [Pb. PMT 1998]

Options:

A) Br<Fe2+<Al

B) Fe2+<Al<Br

C) Al<Br<Fe2+

D) Al<Fe2+<Br

Show Answer

Answer:

Correct Answer: A

Solution:

Reducing power, i.e. the tendency to lose electrons increases as the reduction potential decreases.
