log and ln in Nernst

[Diana_Diep2I]

When do we use log and when do we use ln when using the Nernst equation? Or does it not matter?

[KaleenaJezycki_1I]

It doesn't matter! Its up to you which one you use but make sure you use the correct conversions for which one you choose (2.303)

[Eunice Nguyen 4I]

They're basically the same thing for the Nerst equation:
E=Eo-(RT/nF)lnQ
E=Eo-(2.303RT/nF)logQ
This is because lnx=2.303logx

[Verity Lai 2K]

It doesn’t matter because Lavelle showed us the conversion from log to ln. But in class he told us that biological sciences are more likely to use the log version, however I don’t think it matters in our case.

[cassidysong 1K]

I believe he emphasized the log equation just because it is more relevant to life science but yeah I don't think it matters as long as you remember the conversion factor

[Vinita Saxena 2I]

It doesn't matter, but usually biologists use the log version of the equation

[LNgo 1G]

It doesn’t matter which you use but I think in lecture he said that biologist usually use log because pH is calculated using log.

[ThomasNguyen_Dis1H]

Doesn't really matter. Lavelle only mentioned it since ph is calculated using log so it could be more helpful when you use log in the equation.

[Tiffany_Chen 2K]

Either would work, log is typically used as it is more useful in calculating pH.
