The Nernst equation relates the EMF of a cell to:
The Nernst equation relates the EMF of a cell to:
Show Hint
$E = E^{\circ} - (\text{constant} \times T) \log(\text{Concentration})$. It links potential to both variables.

- Temperature only
- Concentration of ions and temperature
- Pressure only
- Standard potential only
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
The Nernst equation allows for the calculation of cell potential under non-standard conditions.
Step 2: Meaning
The equation is expressed as $E = E^{\circ} - \frac{RT}{nF} \ln Q$.
Step 3: Analysis
In the formula, $T$ represents temperature and $Q$ is the reaction quotient, which depends on the concentrations (or pressures) of the ions and molecules involved.
Step 4: Conclusion
Thus, the Nernst equation specifically relates the Electromotive Force (EMF) to the temperature and the concentration of the reactants and products. Final Answer: (B)
