摘要
Investigations were carried out on the substitution of iodide ion by thiocyanate ion on iodopentaammineruthenium(III), ion in the temperature range 35-50 degrees C. Rate increases linearly with SCN-. A plot of 'K' vs. SCN- shows positive intercept on rate axis, indicating both SCN dependent and SCN- independent pathways for the substitution reaction. Substitution of SCN- on aquapentaammine complex has also been investigated to make a comparative study of the two reactions. Both the reactions follow an associative interchange mechanism.
