Redox Reactions And Electrochemistry Ques 122

Question: The standard electrode potentials of $ Z{n^{2+}}/Zn $ and $ A{g^{+}}/Ag $ are $ -,0.763,V $ and $ +,0.799,V $ respectively. The standard potential of the cell is [KCET 1993]

Options:

A) 1.56 V

B) 0.036 V

C) - 1.562 V

D) 0.799 V

Show Answer

Answer:

Correct Answer: A

Solution:

$ E_{cell}^{o}=E_{Cathode}^{o}-E_{Anode}^{o} $ = $ 0.799-(-0.763)=1.562 $ V
