How are tears useful to us?

Write Nernst equation for a metal and non metal eletrode.

The Nernst equation giving dependence of electrode potential on concentration is

Nernst equation gives the variation of potential of an electrode based on activity of ions temperature and pressure. The equation is E=E^(@) -(2.303RT)/(nF) logQ (or) E=E^@ - (0.0591)/(n) log Q E^@ = Standard potential and 'Q' is the reaction quotient.
