Ncert Exercises & Solutions

Given below are two statements:

Assertion (A):	Current stops flowing when E_cell = 0.
Reason (R):	Equilibrium of the cell reaction is attained.

1.	Both (A) and (R) are true and (R) is the correct explanation of (A).
2.	Both (A) and (R) are true but (R) is not the correct explanation of (A).
3.	(A) is true but (R) is false.
4.	Both (A) and (R) are false.

Hint: At equilibrium, the cell will not work.

At equilibrium, E_cell = 0 and reaction reaches the equilibrium. At equilibrium conditions, the cell will not work and the current stop flowing.
