Reaction of $\left[\mathrm{Ru}\left(\mathrm{NH}_{3}\right)_{5}(\text{isonicotinamide})\right]^{3+}$ with $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+}$ occurs by inner sphere mechanism and rate of the reaction is determined by dissociation of the successor complex. It is due
