Question

Explain Nernst Planck Equation

Answer 1

$\huge\mathcal{Answer}}}$

❤️It describes the flux of ions under the influence of both an ionic concentration gradient ∇c and an electric field

❤️E = −∇φ −∂A∂t.

❤️If the diffusing particles are themselves charged they are influenced by the electric field. Hence the Nernst–Planck equation is applied in describing the ion-exchange kinetics in soils.
