Gibbs free energy

Postby Christina Chang 1C » Fri Feb 08, 2019 12:41 pm

I know that it won’t be on the midterm, but what else does calculating Gibbs free energy tell us besides whether or not the reaction is spontaneous?

It tells you if the reaction is favorable which is based on spontaneity

It also tells us the free energy of a system at any point in time. The fact that it a state function makes it easier to calculate as you would with dH° and dS°.

If the value is negative, then it's spontaneous and favors product formation and if the value is positive, then it's non spontaneous and does not favor formation of products.

It tells us about spontaneity of a reaction, work and can be used to calculate the equilibrium constant.

Also, Dr. Lavelle said in lecture that Gibbs free energy only refers to situations where the system is not at equilibrium, since delta G when the system is at equilibrium is zero.
