Redox Reactions And Electrochemistry Ques 699
Question: The standard electrode potentials of four elements A, B, C and D are -3.05, -1.66, -0.40 and +0.80. The highest chemical reactivity will be exhibited by:
Options:
A) A
B) B
C) C
D) D
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Standard electrode potential i.e. reduction potential of A is minimum $ ( -3.05V ) $ i.e. its oxidation potential is maximum which implies ‘A’ is most reactive chemically.
