E equations and when to use them?

Postby Emily Tam 1k » Fri Mar 15, 2019 9:31 pm

On the constant sheet there are two equations:
E=Eº - RT/nF(lnQ) and E=Eº - 0.05916/n(logQ)

What is the difference between the two? In what situations would i use these equations, or does it not matter?

They're the same equation rearranged. You'd use one over the other depending on the information your given and the information you need to find.

Yes and in the event that you are dealing with a concentration cell the E^o becomes 0
