Redox Reactions And Electrochemistry Ques 215

Question: A galvanic cell with electrode potential of $‘ A^{'} = + 2.23 V$ and $‘ B^{'} = - 1.43 V$ . The value of $E {^{\circ}}_{c e l l}$ is [Pb.CET 2003]

Options:

A) 3.66 V

B) 0.80 V

C) - 0.80 V

D) - 3.66 V

Show Answer

Answer:

Correct Answer: A

Solution:

$E_{A} = 2.23, V > E_{B} = 1.43 V$ So A will act as cathode in galvanic cell. Hence $E_{c e l l}^{0} = E_{C a t h o d e} - E_{A n o d e}$ $= E_{A} - E_{B}$ $= (2.23) - (- 1.43)$ $= 3.66 V$ .
