Standared reduction electrode potenitals of three metals `A, B` and ` C ` are ` =0.5 V, - 3.0 V`, and ` -1.2 V` respectively. The reducing power of these metals are :

Options

A. ` Xgt Y gt Z`
B. Standard electrode potentila fo three metals `X, Y` and ` Z` are `- 1.2 V, + 0.5 V` and `-3 oV` respectively. The reducting power of these metals will be .
C. ` Y gt zgt X`
D. ` Ygt X gt Z`

Answer

B

Explanation

As the value of standrd reduction potental decrase, the reducing power increases i.e.
Reducing power ` Z gt X gt Y`.
