question_answer
The standard reduction electrode potentials of four elements are \[A=-0.250\,\,V\] \[B=-0.136\,V\] \[C=-0.126\,\,V\] \[D=-0.402\,\,V\] The element that displaces A from its compounds is
A) B
B) C
C) D
D) None of these
Correct Answer:
B
Solution :
A is displace from D because D have a \[{{E}^{o}}=-0.402\,\,V\].
