Chemical equilibrium is a state in which no visible changes are observed in the system. However, at the molecular level if changes occur, the chemical equilibrium is at the point where the rates of the forward and reverse reactions are equalized, which results in the quantities of reagents and products present being constant through weather.

Dynamic nature of chemical equilibrium.  Any system in equilibrium is in a dynamic state in which two or more processes are occurring at the same time and at the same speed.  This means that not only one molecule reacts but several, many molecules react.

Homogeneous equilibrium. Â It is the one in which all the participants are in a single phase. The heterogeneous are equilibrium indicates that in the reaction there are different phases


Factors Affecting Chemical Equilibrium Concentration If we lower the concentration of a system in chemical equilibrium, it will move to the side of the equation that has been affected, on the other hand, if the concentration is increased, the equilibrium will move towards the opposite side of the addition

Temperature change When the temperature in an equilibrium system is increased, it will move in the direction that absorbs the applied heat.

It is called activity to the interaction of ions between particles that are excited by means of temperature, pressure and composition has to do with thermodynamics. In Thermodynamics, activity is a measure of an “effec-


The Gibbs free energy variation (ΔH) It measures actual and actual work available for a reaction to undergo a transformation under constant temperature and pressure conditions. Enthalpy (H) and Entropy (S) ΔH> 0 Endothermic reaction (absorbs heat) ΔH <0 Exothermic reaction (releases heat). ΔS> 0 Increases entropy in the system ΔS <0 Decreases entropy in the system.


All solutes that are soluble in water can be: Electrolytes: are those that dissolve in water, conduct electricity. These in turn are divided into: 1. Strong electrolyte: Contains a large number of ions 2. Weak electrolyte: Contains a small number of ions No Electrolytes: They are those that do not conduct electricity when they dissolve in water.

Ph Is the scale for acid-based determined.
