Redox Reactions And Electrochemistry Ques 740
Question: The standard EMF of a cell having one electron change is found to be 0.591 V at $ 25{}^\circ C $ . The equilibrium constant of the reaction is:
Options:
A) $ 1.0\times 10^{30} $
B) $ 1.0\times 10^{5} $
C) $ 1.0\times 10^{10} $
D) $ 1.0\times 10^{1} $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ E_{cell}^{o}=\frac{0.059}{1}\log K_{c} $ $ 0.059=\frac{0.059}{1}\log K_{c} $
$ \therefore $ $ K_{c}=1\times 10^{10} $
