Which of the following equation connects electrode potential to reaction quotient?
Kohlrausch's equation
nernst equation
ohm's equation
Faraday equation
As we have learnt.
It is the potential difference between the two terminals of the cell when no current is drawn from it. It is measured with the help of potentiometer or vacuum tube voltmeter.

Nernst equation
Where E= electrode potential and Q = reaction quotient
Therefore, option(2) is correct
