Question

What is Onsager Conductivity Equation?

Answer

Onsager Conductivity Equation - The equation is valid for highly dilute solutions of strong electrolytes. In the simplest case, for a fully dissociated mono-monovalent electrolyte (such as NaCl), the Onsager equation of electrical conductivity assumes the form J₁ = L₁₁X₁ + L₁₂X₂ J₂ = L₂₁X₁ + L₂₂X₂ Here J₁ is the flow of energy and J₂ the flow of matter. X₁ is the ‘force’ producing energy flow and X₂ that producing matter flow. L₁₁ is the coefficient for thermal conductance and L₂₂ the coefficients for diffusion. The coefficients L₁₂ and L₂₁ represent coupling of the flows with each other.
