Learning Materials
1. The quantitative relationship between reactants
and reaction products of the reaction of equilibrium
2. The equilibrium constant (Kc) the value of
equilibrium constant can be determined by experiment, the value of Kc also
can be predicted if the concentration of
substances in equilibrium is known
3. The equilibrium constant of gas (Kp)
Kp is valid only for reactions involving gases.
Kp is calculated by using the partial pressure of substances that are in
equilibrium
4. The relationship of Kc and Kp
Kp = Kc (RT) Δn
5. The equilibrium of dissociation
Dissociation is the decomposition of one
substance into another, which is more simple
The degree of dissociation is the ratio of moles of a substance that dissociates by the number of moles of the substance at first.
The degree of dissociation is the ratio of moles of a substance that dissociates by the number of moles of the substance at first.
