Practice Problem: Calculating Free Energy Change

We know that the free energy change associated with a process will tell us whether it is spontaneous or not. And we also know that this depends on the change in enthalpy and the change in entropy for that process, as well as the temperature. Give some thermodynamic data, can we calculate the change in free energy for a process? Let's try!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

I was so bad at this in college but your videos have helped me prep these types of questions for the MCATs. I was able to get it right on my own! Thanks so much professor dave!

Professor Dave, this was great! Very good! May I suggest you to explain how to use free Gibbs energy to evaluate the equilibrium constant?

So so much useful.. please sir a video on material, mass, energy, heat balance calculations for Bioprocess

Hi, Prof. Dave! I think you need to change deltaS298 to just S(molar)298. (Third law entropies don't need a delta)

I send flat earthers here so I can hear the distant *pop* of their heads exploding.

I received the notification when I was watching Apple September event. Then I closed it and started to watch this. 😘😊

instead of converting delta s into kj from j, can we do that for delta h?

Are you able to use this at temperatures other than 298K?

Hi Prof, do u mind if I were to clarify questions with you through email, on my assignment?
