Selected Physical Chemistry Experiments in M.Sc. 3rd Semester Course

 

Kinetics (six experiments):
 

Determine the temperature coefficient and energy of activation of acid hydrolysis of methyl acetate, using linear least squares calculation.
 

Study the inversion of sucrose in presence of two acids, polarimetrically using Guggenheim plots, and hence determine the relative strengths of the acids.
 

Study the saponification of ethyl acetate by sodium hydroxide and determine the temperature coefficient and energy of activation.
 

Study the autocatalytic reaction between oxalic acid and KMnO4 and determine the order of the reaction using half-life method
 

Study the mutarotation of glucose in presence of acid by polarimetric method, and investigate the influence of acid strength on the rate of reaction. (Use two conc. of HCl acid, base influence not required)
 

Study the kinetics of oxidation of ethanol by chromium (VI) and hence find the order of the reaction by half-life method.
