calculation of bond dissociation

It is defined as the amount of energy required to break one mole of bonds of a particular type between the atoms of a molecule in the gaseous state. It is expressed in terms of kJ mol - 1 . When a bond is formed between the atoms, energy is released and the bonded at..

Degree of dissociation ( a ) at a particular concentration c is related to the dissociation constant (..

Calculation of Degree of Dissociation - Degree of Dissociation [ a ] - It is defined as the fraction of the total number of molecules undergoing dissociation at a given concentration. Example: If 100 molecules of acetic acid are added to H 2 O of which 10 mol..

Bond Energy or Bond Enthalpy - In chemical reactions the formation of a chemical bond is accompanied by the release of energy. Conversely energy has to be supplied for the breaking of a bond. Bond strengths are commonly described by their bondh..

Dissociation of Solute Molecules - A number of electrolytes dissociate in solution to give two or more particles (ions). Therefore, the number of solute particles, in solution of such substances is more than the expected value. Accordingly, such solutions exhibit higher values o..

It is defined as the fraction of the total number of molecules undergoing dissociation at a given concentration. Example: If 100 molecules of acetic acid are added to H 2 O of which 10 molecules ionise, then or 1) If 0.1M acetic acid has 25% degree of dissociation, what is the c..

Shorter the bond length, larger is the value of bond energy. For example, bond length (154 pm) is larger than C=C bond length (134 pm). Consequently, the dissociation energy of C-C bond (348 kJ mol - 1 ) is smaller than that of C=C ..

The smaller the size of the bonded atoms, the stronger is the bond and larger is the value of bond dissociation energy. For example, the bond dissociation energy of H-H bond in hydrogen molecules is 433 kJ mol - 1 . This is lar..

Nature of C-X Bond - The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the presence of p..

The electronic configuration of fluorine atom is 1s 2 2s 2 2p 5 and therefore, there are 14 electrons in the valence shell of F 2 molecule. The molecular orbital electronic configuration of the molecule is: F 2 : KK ( s 2s) 2 ( s *2s) 2 ( s 2p z ) 2 ( p 2p x ) 2 ( p 2p y ) 2 ( p *2p x ) 2 ( p *2p y..
