If a reaction is exothermic and you decrease the temperature, what happens to K?

K increases, shifts towards the products
How is acidity and basicity determined with oxoacids?
- The more O ions, the stronger the acid.
- Less O ions, the weaker the acid and stronger the base
Lattice energy

The amount of energy required to separate one mole of solid into gas
Mole fraction

Mole solute/mol solution
Freezing point depression

Im (molality) * Kf
Boiling point elevation

Im (molality) * Kb
Osmotic pressure

I * M (solute) *RT

Where R= 0.0821
Raoults Law (vapor pressure lowering)

P (solution)= mole fraction (solute) * Pressure (solvent)
