The sign of entropy change ( ΔS o ) has to be predicted for the given set of reactions. Concept introduction: Entropy: Entropy is a measure of randomness (disorder). If the randomness of a system is increases then its entropy will increase. The value of entropy increasing situations is given below: When a molecule is broken down and gives two or more smaller molecules. When the moles of gas is increases (by the breaking of molecules). Solid changes to liquid or gas state or liquid state changes to gas state.

Solution Summary: The author explains the sign of entropy change for the given set of reactions.
Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
