Redox Reactions And Electrochemistry Ques 647

Question: For a given reaction: $M (x + n) + n e^{-} \overset{}{\to} M^{x +}, {E^{-}}_{r e d}$ 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] $E_{r e d} = E_{r} e d^{^{\circ}} + \frac{0.059}{n} \log \frac{[M^{(x + n)}]}{[M^{x +}]}$ here apart from n, all are known so we can calculate value of n by this equation.
