Effects of temperature on the polarographic behaviour of 3-methyl-(4'-substiotuted-benzeneazo)-2-isoxazolin-5-ones

The polarographic behaviour of 3-methyl-4-(4'-substituted-benzeneazo)-2-isoxazolin-5-ones has been studied in 50 percent (v/v) dimethylfomamide solution in Britton-Robinson buffer of pH 4.1 at differnt temperatures (303.15-333.15 K). The reduction is found to be diffusion-controlled and irreversible at different temperatures. The shift of E1/2 values towards more negative potentials and decrease in the values of αna and kof,h suggest that the electrode reaction becomes more irreversible at elevated temperatures. The thermodynamic quantities have been evaluated.
