Vant hoff factor refers to the ratio of the total no. of particles after dissociation of a solute to the total no. of particles before dissociation of the solute in the solution.
or
it is the ratio of the normal mass of the solute to the abnormal mass of the solute.

Osmotic Pressure: The flow of solvent from solvent side to solution side (across a semi-permeable membrane) can be stopped by applying some extra pressure. The pressure which is just enough to stop osmosis is called osmotic pressure of the solution.
Fore dilute solutions, osmotic pressure is proportional to the molarity (C) of the solution at a given temperature.
Π=CRT
Here, Π is osmotic pressure and R is the gas constant.

Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa. These reactions involve electric charges moving between electrodes and an electrolyte (or ionic species in a solution). Thus electrochemistry deals with the interaction between electrical energy and chemical change.

Mm = {tex}\frac{w}{V}{/tex}
Where;-
M = molarity (in moles/l)
w = the weight of solute (in grams)
m = the molar mass of the solute (g/mole)
V = the volume of the final solution after complete dissolution (in litres)

Solubility of H2S gas = 0.195 m
= 0.195 mole in 1 Kg of the solvent (water)
1 Kg of the solvent (water ) = 1000 g
{tex}= \frac{{1000g}}{{18\,g\,mo{l^{ - 1}}}}{/tex} = 55.55 moles
Mole fraction of H2S gas in the solution (x) {tex} = \frac{{0.195}}{{0.195 + 55.55}}{/tex}
{tex}= \frac{{0.195}}{{55.745}}{/tex}= 0.0035
Pressure at STP = 0.987 bar
Applying Henry's law
{tex}P_{H_2S}=K_H\times X_{H_2S}{/tex}
{tex}K_H=\frac{P_{H_2S}}{X_{H_2S}}{/tex}
{tex}= \frac{{0.987\,bar}}{{0.0035}}{/tex}
= 282 bar

Cr2+ - d4 configuration gets converted to Cr3+ - d3 has half-filled t2g orbital makes it good reducing agent while In case of Mn3+- d4 Configuration gets converted to Mn2+ - d5 configuration giving half –filled d-configuration has more stability which makes it good oxidising agent.

he valence bond theory could not explain the stability of coordination compounds. It also failed to throw a light on the differences between strong and weak ligands. Therefore, scientists proposed the crystal field theory.
According to this theory, the metal-ligand bond acts as an ionic bond arising purely from the electrostatic interactions between the metal ions and ligands. This theory takes anions as point charges and neutral molecules as dipoles. When the transition metals do not bond to any ligand, their d orbitals degenerate. This means that they have the same amount of energy.
When they start bonding with other ligands, the d orbitals split apart and become non-degenerate. This bonding occurs mainly due to different symmetries of the d orbitals and the inductive effect of the ligands on the electrons. The pattern of the splitting of d orbitals depends on upon the nature of crystal field.
