problems involving calculation of kc when dissociation of an electrolyte/gas occurs in a reversible reaction

Most of the reactions are reversible in nature. In these reactions both the forward and the backward reactions occur simultaneously. For e.g., in the following reaction, the forward reaction is exothermic; but the backward ..

.e., the equilibrium position) no movement of children on the see-saw occurs. Static Equilibrium In the case of reversible reaction, however a static equilibrium is not being established. In the case of ammonia, using deuterium, D (an isotope of hydrogen) it has been p..

Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solution. Most common ways of expressing concentration of any solute in a solution a..

This is also a type of reversible reaction, in which heat decomposes a substance. But if the products are not allowed to escape, then on cooling, they recombine to from the original substance. Nitrogen dioxide decomposes above 50 o C to form nitric oxide and oxygen. But, if t..

Usually chemical reactions proceed only in one direction. But in some cases the reaction reverses itself. Example, when steam is passed over red hot iron, magnetic oxide of iron and hydrogen gas are formed. If hydrogen gas is passed over heated mag..

. In such irreversible reactions, the reactions occur only in the forward direction. These reactions go to completion and no starting materials are left. However, reversible reactions do not go to completion. When these reactions..

Only when a particle loses electrons can the other particle accept electrons. In other words, a particle can accept electrons only if another particle gives out electrons. This electron-transfer process is possible only when both species are present in the reaction. Hence, oxidation and ..

But for having unique value of the reaction rate (independent of the concentration term chosen), we divide the rate of the reaction, defined with respect to any of the reactants or products by the number of moles involved in the reaction. Thus, for the above ..

Mechanism of Reaction - A balanced chemical equation represents the overall result of a chemical reaction. However, at the molecular level, more than one reaction step might be involved. Most reactions can be broken down into a sequence of elementar..

. D m the mass defect or the mass converted into energy is given by D m = 236.127 - 235.846 = 0.281 amu 1 amu = 931.48 MeV \ Energy released = 0.281 amu = 931.48 x 0.281 = 261.75 MeV The neutrons emitted from the fission of first uranium atom hit other uranium nuclei and cause their fission resulti..
