Derivation of poisson and nernstplanck equations in a bath and channel from a molecular model z. Show xa may 23, 2011 looks good to me to, but just to improve the style of your proof. I hope this derivation of the pervasive nernst equation helps give you a feel for the thinking behind its development as well as some inroad into practically applying the equation to problems in neuroscience. Derivation of poisson and nernstplanck equations in a. Solve x4x3x2x20 tiger algebra solver a free, online. Science and technology, general ecuaciones matematicas investigacion matematica matematicas. The nernst equation calculates the equilibrium potential also referred to as the nernst potential for an ion based on the charge on the ion i. The nernst equation is derived from the emf and the gibbs energy under nonstandard conditions. We can calculate m because the line goes through points 2,0 and 0,3. The nernst equation links the equilibrium potential of an electrode, e e, to its standard potential, e 0, and the concentrations or pressures of the reacting components at a given temperature. When a product of two or more terms equals zero, then at least one of the terms must be zero. Remember you can also determine the equation of a line from its graph if you get two points of the line.
This seems a very daunting task, but its actually quite easy. Please note that the unit of temperature used in the nernst equation is the kelvin. As to the analytical solution of the nernst planck equation in twodimensional space and time coordinates, some parameters are assumed. The analytical solution of the nernstplanck equation in unidirectional space and time coordinates is described by 21.
