For example, At equilibrium the rate of forward reaction is equal to the rate of backward reaction. Equilibrium mixture: The mixture of reactants and products in the equilibrium state is called an equilibrium mixtures. Based on the extent to which the reactions proceed to reach the state of equilibrium, these may be classified in three groups: i The reactions which proceed almost to completion and the concentrations of the reactants left are negligible. The system here is in dynamic equilibriums and following can be inferred. For example, when solid iodine is placed in a closed vessel, violet vapours start appearing in the vessel whose intensity increases with time and ultimately, it becomes constant.

Ionic Equilibrium Notes Pdf

In a chemical reaction , chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactants and products. Such a state is known as dynamic equilibrium. The concept of chemical equilibrium was developed after Berthollet found that some chemical reactions are reversible.

DefineBronsted acid and base Bronsted acid is a substance which gives proton or proton generator or protogenic where as Bronsted base is proton acceptor or takes proton or protophilic. Define Lewis Acid and Lewis Base. Lewis acid is a substance which accepts a lone pair of electron and Lewis base is a substance which donates a lone pair of electron. The condition for Lewis base is it should have at least one lone pair and for the Lewis acid it should have at least an empty orbital to accommadate the pair of electrons received. What is dissociation constant of an acid? How it is used to know acidic nature of an acid? The equilibrium constant of the dissociation of an acid is known as dissociation constant of acid Ka If Ka has higher value indicates more dissociation of acid then it is strong acid where as weak acid has lower Ka value.

Equilibrium Class 11 Notes Chemistry Chapter 7

The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium , a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change. For a given set of reaction conditions, the equilibrium constant is independent of the initial analytical concentrations of the reactant and product species in the mixture. Thus, given the initial composition of a system, known equilibrium constant values can be used to determine the composition of the system at equilibrium. However, reaction parameters like temperature, solvent, and ionic strength may all influence the value of the equilibrium constant. A knowledge of equilibrium constants is essential for the understanding of many chemical systems, as well as biochemical processes such as oxygen transport by hemoglobin in blood and acid-base homeostasis in the human body.

ОБЪЕКТ: ДЭВИД БЕККЕР - ЛИКВИДИРОВАН Как во сне она направилась к главному выходу из шифровалки. Голос Грега Хейла эхом отдавался в ее сознании: Сьюзан, Стратмор меня убьет, коммандер влюблен в. Она подошла к огромному круглому порталу и начала отчаянно нажимать кнопки.

 - Потом мы запустим его снова, а Филу скажем, что ему все это приснилось. Стратмор задумался над ее словами, затем покачал головой: - Пока не стоит. ТРАНСТЕКСТ работает пятнадцать часов. Пусть пройдут все двадцать четыре часа - просто чтобы убедиться окончательно. Сьюзан это показалось разумным. Цифровая крепость впервые запустила функцию переменного открытого текста; быть может, ТРАНСТЕКСТ сумеет взломать шифр за двадцать четыре часа. Но честно говоря, она в это уже почти не верила.

acceptor(base), and the NH4+ ion acts as a proton donor (acid). Substances such as water, ions such as hydrogen sulphate ion are both Bronsted Lowry acids.
