Question

Does cell potential have to be positive


Open in App
Solution

Explanation:

The cell potential has to be positive such as

  1. The cell potential must be positive for galvanic cells.
  2. To understand cells' potential we use the relationship of the galvanic cell as:

G=-nFEcell

Where n is the number of electrons, F is the electrostatic force, and Ecell is the cell potential.

Therefore from the galvanic cell relationship, a positive cell potential tells us that both the reaction is spontaneous and G is negative.

Hence, cell potential has to be positive for galvanic cells.
