ENTROPY

Entropy change in Chemical Reactions

∆So = ∑Soproducts -∑Soreactants

Factors Which Affect Entropy

• Temperature - as temperature increases so does entropy.
• Number of particles - as the number of particles increases so does entropy.
• Complexity - the more complex the system the greater the entropy.

Entropy (S) is the extent of disorder of matter and/or energy in a system.

Entropy along with enthalpy (endo or exo) can be used to determine the sponteneity of a reaction.
