TI  - Kinetics and mechanism of mercury(II)-catalysed replacement of cyanide in 
      hexacyanoferrate(II) by p-nitrosodiphenylamine.
PG  - 591-7
AB  - The mercury(II)-catalysed replacement of cyanide in hexacyanoferrate(II) by 
      p-nitrosodiphenylamine (p-NDA) in aqueous solution has been investigated 
      spectrophotometrically by measuring the change in absorbance of the green complex 
      ion, [Fe(CN)(5).p-NDA](3-), at 640 nm. Activation parameters of the catalysed and 
      uncatalysed reactions have been calculated. The effects of the dielectric 
      constant and water content of the medium on reaction rates are used to explain 
      the formation of a polar activated complex and suggest an I(d) mechanism for the 
      catalysed reaction. The varying catalytic activity of Hg(II) as a function of 
      concentration has been discussed.
