Assertion (A) `E_("cell")` should have a positive value for the cell to function,
Reason(R) `E_("cathode")ltE_("anode")`

A

Both assertion and reason are true and the reason is the correct explanation of assertion.

B

Both assertion and reason are true and the reason is not the correct explanation of assertion.

C

Assertion is true but the reason is false.

D

Both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
Correct Reason: `E_(cell)=E_("cathode")-E_("anode").E_(cell)` is +ve when `E_("cathode")gtE_("anode")`.

What does the negative value of E_("cell")^(@) indicate?

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.

In an electrochemical cell, anode and cathode are:
