Yogita Ingle 6 years, 3 months ago

Molar conductivity of a solution at a given concentration is the conductance of volume V of a solution containing one mole of electrolyte kept between two electrodes with an area of cross-section A and distance of unit length.

Ʌm = К/c

Here,

c = concentration in moles per volume
К = specific conductivity
Ʌm = molar conductivity.

Yogita Ingle 6 years, 3 months ago

The crystal field theory was proposed by Hans Bethe and VanVleck. This theory gives satisfactory explanation for the bonding and the properties of complexes than the valence bond theory.

Assumptions of Crystal field theory:

The interaction between the metal ion and the ligand is purely electrostatic.

Negative ligands are treated as point charges and neutral ligands are treated as dipoles.

The five d-orbitals in an isolated gaseous metal atom (or) ion are degenerate.

The repulsions between the electrons in the metal ion and the ligands increases the energy of the d-orbitals and lifts the degeneracy in d-orbitals. This results in the d- orbitals getting split.

What is rate law?

Posted by Sangita Sonkusare 6 years, 4 months ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 6 years, 4 months ago

Rate law

The representation of rate of reaction in terms of molar concentration of the reactants participating in a reaction raised to some power is called rate law.
It is also called rate expression or rate equation.
Consider a reaction:

2NO (g) + O₂ (g) --> 2NO₂

Rate ∝ [NO]²

Rate ∝ [O₂]

Combining these two rates we derive

Rate ∝ [NO]² [O₂]

Rate =k [NO]² [O₂]

Where k is the proportionality constant with a definite value at a specific temperature for a specific reaction and is called Rate Constant.
Rate law expression = -d[R]/ dt = k [NO]² [O₂]

Achyut Singh 6 years, 4 months ago

Before mixing chlorobezene and bromobenzene they have van der waals attraction force between them in pure state . And after mixing them the attraction force is very nearly the same so no change in attraction force after mixing so an ideal solution is formed . But in acetone and chloroform mix. due to presence of H bonding in pure state and mere van der waals force in mix. state change in attractive force is noticed resulting in deviation from ideal nature.

Early lanthanoids have tight atomic bonding that of early actanoids thats why early lanthanoids need more energy to break the bond between an atom so it posses high ionisation enthalpy
