Question

Assertion :EMF of the cell is the potential difference between the electrode potentials of the cathode and anode when no current is drawn through the cell. Reason: Anode is kept on the right side and cathode on the left side while representing the galvanic cell.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

EMF- Electromotive force

$E_{cell}=E_R-E_L$

It is the difference in the reduction potential of reaction taking place at cathode and anode respectively.

Galvanic cell- Anode is on left as oxidation takes place

Cathode is on right as reduction takes place.

$\underset{\left(anode\right)}{\underset{}{Zn|Z{n}^{2+}|}}\underset{\left(cathode\right)}{\underset{}{|C{u}^{2+}|Cu}}$
