Redox Reactions And Electrochemistry Ques 133
Question: Consider the reaction $ M_{(aq)}^{n+}+n{e^{-}}\to {M_{(s)}} $ . The standard reduction potential values of the elements $ M_1,,M_2 $ and $ M_3 $ are $ -0.34V,,-,3.05,V $ and $ -1.66,V $ respectively. The order of their reducing power will be [NCERT 1990]
Options:
A) $ M_1>M_2>M_3 $
B) $ M_3>M_2>M_1 $
C) $ M_1>M_3>M_2 $
D) $ M_2>M_3>M_1 $
Show Answer
Answer:
Correct Answer: D
Solution:
The reducing power decreases as the reduction potential increase (becomes less negative).
