Re: Gibb's Free Energy
Gibb's Free Energy is energy available to do work in reaction. It's different from other energy functions (like enthalpy) because it takes energy loss due to entropy into account, since real work is not 100% reversible.
It's mainly used to tell If a reaction is spontaneous.

Re: Gibb's Free Energy
Conceptually, I think it may be most important to think about Gibb's Free Energy as a convenient state function used to determine whether a reaction will proceed spontaneously. As previously stated, it is a measure of energy available to do work in a system.
Re: Gibb's Free Energy
Gibbs Free Energy is the most accurate way of measuring whether a reaction will be spontaneous. If it's negative, the reaction is spontaneous. If it's positive, the reaction isn't spontaneous.

Re: Gibb's Free Energy
Gibbs Free Energy is the amount of thermodynamic potential energy available to do work. The equation for it is usually used to determine the energetics of a system, such as if it is spontaneous (Negative deltaG) or not.

Re: Gibb's Free Energy
Can one actually calculate amounts of G contained in a substance, or only transferred amounts?

Re: Gibb's Free Energy
Gibbs Free Energy is the amount of free energy available to do work. It is a state function, so only the initial and final amounts matter.
