Redox Reactions And Electrochemistry Ques 567
Question: The standard EMF for the cell reaction, $ Zn+C{u^{2+}}\xrightarrow{{}}Cu+Z{n^{2+}} $ is 1.1 volt at $ 25{}^\circ C. $ The EMF for the cell reaction, when $ 0.1,MC{u^{2+}} $ and $ 0.1MZ{n^{2+}} $ solutions are used, at $ 25{}^\circ C $ is
Options:
A) 1.10 V
B) 0.10 V
C) $ -1.10V $
D) $ -0.110V $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] Since concentration of ions is the same hence $ E_{cell}=E_{cell}^{{}^\circ } $
