cell potential equations

Postby Salma Sudarmadji 2I » Sun Mar 19, 2017 12:01 am

For the equation E= E -RT/nF lnQ and E=E- 0.05916/n logQ, I get different answers. Is one preferred over the other? Or will both answers be accepted?

The two should give equivalent answers as the change from log to ln is accounted for. Make sure the constants are the right units/value?

Maybe you made some calculation error along the way or plugged numbers in your calculator wrong. They should be the same.

depending on your calculator, you might have to put in log with a base of 10 explicitly since some calculators imply that base while others dont
