equilibrium potential

equilibrium potential

[‚ē·kwə′lib·rē·əm pə′ten·chəl]
(physical chemistry)
A point in which forward and reverse reaction rates are equal in an electrolytic solution, thereby establishing the potential of an electrode.

The Nernst equation links the equilibrium potential of an electrode, Ee, to its standard potential.
Depending on lithium ion concentration at the surface of a given solid particle, there is an equilibrium potential [U.sub.ref] at which intercalation and de-intercalation reactions occur at equal rates, denoted as [i.sub.0].

Walsh [16] suggested that the details of the cell's equilibrium potential could be used to describe the thermodynamics of the electrochemical system.
To determine the equilibrium potential for GABA (EGABA) a second-order polynomial curve was fitted to I-V relationships (pClamp 10).
1, but now with a slope of- 0.059 V/pH since the equilibrium potential for these reactions depends on the pH of the solution.
Polarization refers to the additional potential required above the equilibrium potential to drive the deposition of the metal to be plated.
That can be explained because the potential into the open circuit polarisation is measured into statically conditions and in the Evans method into dynamic conditions (the potential applied on the electrode being different to the equilibrium potential).
The equilibrium potential for this reaction depends on pH and on the HZn[O.sub.2.sup.-] concentration:
The reversal potential of the currents elicited by the active extracts was -17 [+ or -] 2 mV and was similar to the chloride equilibrium potential in oocytes.
Slow voltage ramps (-130 to 20 mV) revealed that the outward current induced by NE reversed at the predicted equilibrium potential for potassium ([K.sup.+]) ions and showed prominent inward rectification, suggesting that NE activates G protein-coupled inwardly rectifying [K.sup.+] channels (GIRK) channels in these interneurons.
