Gibb's Free Energy?

[Iceman]

So, i'm sitting in my Physics class, the bell goes, and everyone packs up, my teacher screams as we're all leaving "HOMEWORK: FIND OUT WHAT GIBB'S FREE ENERGY THEORY IS!", and after a google search, i find nothing.

 

So i thought i'd ask here!

Gibb's Free Energy is the relationship between enthalpy and entropy, to help determine whether a reaction will be spontaneous or not.

 

If the enthalpy is negative and entropy is positive, the reaction will always be spontaneous. With the opposite (enthalpy positive, entropy negative) the reaction will never be spontaneous.

 

Forumla: G = (Change in Enthalpy) - (Temperature)(Change in Entropy)

Thanks Radagast, i just wrote all that into my book how i've understood it now that you've explained it..let's just hope my interpretation of what you just said is right

No problem.
