Physical Chemistry    (Any four)                                                             24 hrs

a) To determine the mutual solubility curve for phenol – water system and their consolute point.

b)  To study the effect of a solute (NaCl/succinic acid) on the critical solution temperature of two partially miscible liquids (e.g. phenol-water system) and to determine the concentration of that solute in the system.

c)  To determine the transition temperature of given substance by thermometric method.

d)  First order kinetics- Hydrolysis of methyl acetate catalyzed by HCl.

e)  Second order kinetics- Saponification of ethyl acetate (initial concentration of both the reactants are same).

f)   Determination of freezing point depression constant of camphor using Rast method.
