### Cell Potential

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

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.

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.

Both of these equations are the same. constants R, T, F = to .05916

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

These equations are equivalent to each other, it is just that one is simplified.

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.

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.

They're the same, you can use either

when you do you switch the signs of given cell potentials?
