Question

Explain the effect of concentration of emf of cell (nerst equaction)

Answer 1

The emf of a cell depends on the concentrations of ion and on gas pressures. Nernst equation relates the cell emf's for various concentrations and gas pressures to standard electrode potentials.

Answer 2

Answer:

$hey dear ,$

if the concentrations of reactants increase relative to those of products, the cell reaction becomes more spontaneous and the emf increases. Conversely, if the concentrations of products increase relative to reactants, the emf decreases.

the cell because you are putting the system further out of equilibrium. Because the concentration in only one side of the cell has changed, the concentration gradient across both sides of the cell becomes steeper .
