Just for kicks. I tried calculating Keq from Gibb's free energy. This should be a straight forward calculation, but the answer is no where near close.(adsbygoogle = window.adsbygoogle || []).push({});

Here is my calculations in SAGE:

sage: R=8.314; T=298; G=237000 ; Keq=var('Keq'); f=G+R*T*log(Keq)

sage: f.solve(Keq)

[Keq == e^(-59250000/619393)]

sage: float(e^(-59250000/619393))

2.8588096844432612e-42

Note the positive sign before R, that is because when I solve for Keq sage assumes f=0.

I assume using the -(G) should give the self dissociation constant for water. That is 10^(-14)

Thanks,
