If the 0.05 molar solution of `M^+` is replaced by a 0.0025 molar solution, then the magnitude of the cell potential would be ( Ecell = 70mV) :

A

35 mV

B

70 mV

C

140 mV

D

700 mV

Text Solution

Verified by Experts

The correct Answer is:
C
`E_("cell") =0 `, for every concentration cell
`E= 0.. 0.59//n log [M^+]` anode `//[M^+]` cathode
`=+ 153` mV
It is close to 140 m V
