Why is the potential difference between the terminals of a battery is not always equal to the e m f of a battery

The average kinetic energy of the molecules in a gas sample depends only on the temperature, 𝑇. However, given the same kinetic energies, a lighter molecule will move faster than a heavier molecule, as shown in the equation for rms speed rms speed=3𝑅𝑇ℳ‾‾‾...
