when do you use each of the equations and what is the difference?
E = E° -RT/nF * ln Q
E = E° -0.05916 V / n * log Q

Re: Cell Potential
You can use either of the equations cause they are the same. The second equation essentially combines the R, T, and F to get 0.05916 and then takes into account the change from ln to log. Generally log is more efficient to use for biochemistry purposes rather than ln but both are valid.

Re: Cell Potential
since R T and F are all constants in standard conditions, these three constants can be multiplied and calculated to be 0.05916, just to simplify the process of calculations.

Re: Cell Potential
These equations are essentially the same so you can use them interchangeably depending on which information you have.

Re: Cell Potential
These equations can be used in the same situation, however the one with a number already in it has been simplified with the entry of variables already.

Re: Cell Potential
Because R, T and F are constants at standard conditions, the second equation is the same as the first equation with the constants computed into a single constant.
