Chapter 12 Gaseous Chemical Equilibrium

Chapter 12 Gaseous Chemical Equilibrium. The Concept of Equilibrium. Chemical equilibrium occurs when a reaction and its reverse reaction proceed at the same rate. The Concept of Equilibrium. As a system approaches equilibrium, both the forward and reverse reactions are occurring.

Aqueous Solutions and Solubility Equilibria

Aqueous Solutions and Solubility Equilibria. Chapter 9. 9.1 The Acid-Base Properties of Salt Solutions. Salt: any ionic compound that is formed in a neutralization reaction from the anion of an acid and the cation of a base. E.g. HCl ( aq ) + NaOH ( aq ) ? NaCl ( aq ) + H 2 O(l).

Applications of Aqueous Equilibria

Applications of Aqueous Equilibria. Chapter 15. Common Ion Effect. When a solution of a weak electrolyte is altered by adding one of its ions from another source, the ionization of the weak electrolyte is suppressed. This is referred to as the common ion effect.

Predicting if a Reaction is in Equilibrium Trial Keq Lesson 9

Predicting if a Reaction is in Equilibrium Trial Keq Lesson 9. The Keq is a constant- a number that does not change. Changing the volume, pressure, or any concentration, does not change the Keq. Only temperature changes the Keq If the [Reactant] is increased the reaction will shift.
