concentration of reactants/products effect equilibrium

If a system is at equilibrium and the concentration of one of the species involved in the reaction is increased, the system will readjust so as to decrease the concentration of that species. Thus, the reaction will proceed in such a manner so as to consume some of the..

Requirements: 6g of granular zinc 10 mL of 1 M HCl, 10 mL of 2 M HCl, A graduated syringe and a boiling tube. The syringe is attached to the boiling tube and the reaction is carried out with 3g of zinc and 5 mL of 1 M HCl and next with 3g of zinc and 5 mL of 2 M HCl. The volume of the gas at time i..

The rate of a reaction generally increases with increase in concentration of the reactants. For a reaction to take place between two molecules, they must collide or come into contact. The probability of such collisions increase with the increase in the concentration o..

The effect produced due to the addition of an inert gas (which does not react with any of the reactants and products) on the equilibrium of a reaction, can be predicted qualitatively as follow..

.e. endothermic direction. The increasing temperature results in a shift of the reaction towards left (reactant side). This will result in the formation of lesser amount of ammonia. On the other hand, when the temperature of this system is lowered, it will favour the exothermic direction ..

A reversible reaction attains equilibrium when the opposing reactions occur at an equal rate. Therefore, if a reaction at equilibrium is subjected to some change it changes the rate of one reaction more than the other. By changing the concentration, temperature or pres..

The value of the equilibrium constant also depends upon the units in which concentrations is expresse..

The value of Kw varies with the change in temperature. The values of [H 3 O + ] and [OH - ] are always equal to each other at all temperatures but the values of K w are different at different temperatures. The value of K w increases with the rise in temperature. This is because increase in te..

In 1909, Sorensen introduced a term for expressing the concentration of hydrogen ions, which give an idea about the acidic and basic characters of the aqueous solution. This term was called 'pH' which means the 'power of hydrogen ions'. The pH is defined as "the negative logarithm of the ..

The state of reversible reaction at which the concentrations of reactants and products do not change with time is called a state of chemical equilibrium. This state can be recognized by the constancy of certain measurable properties such as pressure, density,..
