For a p n junction, letting C _ A ( x ) and C _ D ( x ) be the concentrations of acceptor and donor atoms respectively, and letting N _ 0 ( x ) and P _ 0 ( x ) be the equilibrium concentrations of electrons and holes respectively, yields, by Poisson's equation:

More ammonia would be produced if the reaction was run at a lower temperature, but a lower temperature also lowers the rate of the process, so, in practice ( the Haber process ) the temperature is set at a compromise value that allows ammonia to be made at a reasonable rate with an equilibrium concentration that is not too unfavorable.

It transpired that ?-NAD ( P ) H molecules are not substrates for renalase; instead 6-dihydroNAD ( 6DHNAD ) was identified as the substrate, a molecule with highly similar spectrophotometric characteristics and equilibrium concentrations as those reported for ?-NAD ( P ) H . 6DHNAD is an isomeric form of ?-NADH that carries the hydride in the 6-position of the nicotinamide base as opposed to the metabolically active 4-position.

Where q _ e is equilibrium adsorbed concentration of adsorbent in mg / g, Q ^ 0 is maximum adsorbed concentration of adsorbent in mg / g, \ epsilon _ { sw } is the effective adsorption potential equal to-RT \ ln { C _ e \ over C _ s }, C _ e is equilibrium concentration of adsorbent in the solution phase in mg / L, and C _ 0 is the adsorbent solubility in water in mg / L.

:: : : : Also, I don't know the inner workings of modern hemodialysis machines, but countercurrent exchange lets you get well beyond " equilibrium concentration " ( average of inside and outside ), and even a more rapid same-direction flow system could do that and use large volumes of extraction liquid ( which could be themselves cleansed and recycled ), whereas soaking in a bath you have limited talk ) 04 : 33, 26 August 2011 ( UTC)
