Energetics

Energetics. Exothermic and Endothermic reactions. Energy = force x distance (Joules). In chemical reactions, we need energy usually in the form of heat. Energy is absorbed to break the bonds of the reactants and energy is given out when new bonds are formed in the products.

Solubility Equilibrium

Solubility Equilibrium. In saturated solutions dynamic equilibrium exists between undissolved solids and ionic species in solutions Solids continue to dissolve and ion-pairs continue to form solids. The rate of dissolution process is equal to the rate of precipitation.
