H + Entropy C—H H ASo change in randomness, disorder freedom of movement Increasing heat, volume, or number of particles increases entropy Spontaneous reactions maximize disorder and minimize enthalpy In the equation AGo= AHo TAso the entropy value is often small Chapter 4 15Chapter 4 15 Entropy • DSo = change in randomness, disorder, freedom of movement. • Increasing heat, volume, or number of particles increases entropy. • Spontaneous reactions maximize disorder and minimize enthalpy. • In the equation DGo = DHo - TDSo the entropy value is often small. =>
