Entropy (S): quantitative measurement of disorder
ΔS < 0: decreasing disorder
ΔS > 0: increasing disorder
Gibbs Free Energy (ΔG): favorability/spontaneity
ΔG < 0: FAVORABLE; spontaneous; the reaction releases energy; proceeds without the input of energy
ΔG> 0: NOT FAVORABLE; not spontaneous; requires energy to proceed
REMEMBER when looking at our definition of spontaneous google reads “performed or occurring as a result of a sudden inner impulse or inclination and without premeditation or external stimulus.” Do not think of this as a random occurrence, but the favorability to happen without the input of energy
