Video Summary
The Nernst equation is a mathematical relationship that explains how a Galvanic cell works and allows us to find the instantaneous voltage of a cell at a specific moment in time.
Its expression is:
E = E0 - (RT/zF)lnQ
Where:
E is the potential difference across the membrane (in volts) E0 is the equilibrium potential for the ion (in volts) R is the universal gas constant T is the temperature (in Kelvin) z is the charge of the ion F is the Faraday constant Q is the reaction quotient
