Define Van't Hot Factor.

A solute 'A' undergoes association in a medium as nAiffA_n If the degree of association is 'alpha' , then Van't Hoff factor may be given as :

Acetic acid dimerises in benzene solution, The Van't Hoff factor for the dimerisation of acetic acid is 0.8. The % of dimerisation of acetic acid is

A 0.5 percent aqueous solution of KCl was found to freeze at 272.76K. Calculate the Van't Hoff factor and degree of dissociation of the solute at this concentration (K_(f)" for water = 1.86 k.kg.mol"^(-1)) . Normal molar mass of KCl = 74.5.

What is the maximum value of van't Hoff factor for AlCl_3 ?

The Van't Hoff factor of 0.005M aqueous solution of KCl is 1.95. The degree of ionisation of KCl is

An aqueous solution of 0.01 M CH_3COOH has Van't Hoff factor 1.01. If pH=-log [H^+] , pH of 0.01 M CH_3COOH solution would be

When solute associates in a solution, the value of Vant Hoff factor is,

A storage battery contains a solution of H_2SO_4 38% by weight. At this concentration, van't Hoff factor is 2.5. At what temperature will the battery contents freeze? ( k_f for water = 1.86 K kg mol^-1 )

0.6 mL of acetic acid (CH_3COOH) , having density 1.06g mL^-1 , is dissolved in 1 litre of water. The depression in freezing point observed for this strength of acid was 0.0205^@C . Calculate the van't Hoff factor and the dissociation constant of acid

The depression in the freezing point of a benzene solution containing 0.784g of Acetic acid dissolved in 100ml of benzene is 0.35k. Calculate the van't Hoff factor and the degree of association of the solute at this concentration (k_(f)" for benzene = 5.10 k.kg.mol"^(-1)," molar mass of acetic acid is 60.01").
