Question

Consider the following reduction processes : Al 3+ + 3e – Al(s), E o = –1.66 V Fe3+ + e– Fe2+, Eo = +0.77 V Co3+ + e– Co2+, Eo = +1.81 V Cr3+ + 3e– Cr(s), Eo = –0.74 V The tendency to act as reducing agent decreases in the order :

(A) Al > Cr > Fe 2+ > Co 2+
(B) Al > Fe 2+ > Cr > Co 2+
(C) Al > Cr > Co 2+ > Fe 2+
(D) Cr > Fe 2+ > Al > Co 2+
