Spontaneous reactions

always take place at a rapid rate

are always exothermic

always release free energy

always result in increased disorder of the system

If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster

For the following, determine the type of reaction and then give products.
