Problem: The standard cell potential for a dry cell battery is 1.56 V. What is the standard free energy change (kJ) for this cell?

FREE Expert Solution

We’re being asked to determine standard free energy change (kJ) (ΔG) for the drycell.


The relationship between ΔG and Ecell is:


G° = -nFE°cell

where:

n = mol e- transferred 

F = faraday's constant = 96485 C/(mol e-)
