Redox Reactions And Electrochemistry Ques 647
Question: For a given reaction: $ M(x+n)+n{e^{-}}\xrightarrow{{}}{M^{x+}},{E^{-}}_{red} $ is known along with $ {M^{(x+n)}} $ and $ {M^{x+}} $ ion concentrations. Then
Options:
A) n can be evaluated
B) x can be evaluated
C) $ ( x+n ) $ can be evaluated
D) $ n,x,( x+n ) $ can be evaluated
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ E_{red}=E_red^{{}^\circ }+\frac{0.059}{n}\log \frac{[{M^{(x+n)}}]}{[{M^{x+}}]} $ here apart from n, all are known so we can calculate value of n by this equation.
