Measuring ∆G°

Postby ng1D » Sat Feb 08, 2020 8:12 pm

In class on Friday, it was mentioned that ∆G°is not measured directly. What does it mean that ∆G°is not measured directly?

I think it means that it is very difficult to measure ∆G° in the lab, so the best way to determine it's value is through calculations with the gibbs energy equation. Hope this helps

Yes, I agree! I remember it being mentioned in lecture that it would be meaningless to try to actually measure free energy alone, so the equation must be used in order to find the value of the standard change in Gibbs free energy.
