Question

Whats ln10?give an ex. for nernst equation

Answer 1

ln10 is the natural logarithm of 10, or 2.30

The Nernst equation is

Ecell = E°cell - (RT/zF) ln Q

Where Q is the reaction quotent; that is, how far out of equillibrium the reaction is. The reaction is in equilibrium when Q = Keq. If Q = 2.30, then the cell potential has changed from equilibrium, and it will seek to attain equilibrium (through generation of electomotive force).
