### Usage for Nernst equation

What does it mean by non standard conditions when determining the direction of electron transfer?

### Re: Usage for Nernst equation

standard conditions are a specific ratio of products to reactants and if the ratio is not that then you have to use the nernst equation

The Nernst equation is used to determine the nonstandard cell potential. Given the standard cell potential, you can use the equation to determine how cell potential changes in relation to temperature and concentrations of the species.

Just to clarify, standard conditions normally means 25 C, 1 atm and 1 M. The equation is used to find the cell potential when the cell is not under these conditions (eg 2 M or 50 C)

are you referring to K? what else would a specific ratio be

I’m pretty sure standard conditions are just 1 M and 25°C.
