Subject: Inorganic Chemistry · Chapter: Coordination Chemistry · Topic: Reaction Mechanisms Substitution · Exam: NET DEC 2015 · Marks: 2 · Difficulty: Medium
The correct statement about the substitution reaction of $\left[\mathrm{Co}(\mathrm{CN})_{5}\mathrm{Cl}\right]^{3-}$ with $\mathrm{OH}^{-}$ to give $\left[\mathrm{Co}(\mathrm{CN})_{5}(\mathrm{OH})\right]^{3-}$ is,
(a)it obeys first order kinetics
(b)its rate is proportional to the concentration of both the reactants
(c)it follows the $\mathrm{S_{N}}1_{\mathrm{CB}}$ mechanism
(d)its rate is dependent only on the concentration of $[\mathrm{OH}]^{-}$
