o
Zn 2 +
With time the concentration of
o The concentration of Cu 2 +
o Voltage reading of the cell on the voltmeter decreases .
o After some time there is no alteration in the concentration of Cu 2 + and Zn 2 + ions and the voltmeter gives zero reading . At this point of time equilibrium has been reach
o The Nernst equation for the reaction is :
o But at equilibrium ,
At T = 298 K .
The equation can be rewritten as
