All bimolecular reactions reported in this paper are of the type (1) and were performed under pseudo-first-order conditions ([X-] ≫ [R+] and [X-] is considered constant during the reaction), R+ + X- ⇄ k- k R-X. The kinetic equation for this case is d [R+] dt =k [R+] [X-] - k- [R-X]. After integration we obtain [R+] t = [R+] 0 e- k1ψ t, where k1ψ =k [X-] + k-. We recorded the decays of the absorption of carbenium cations R+, in most of the cases at different concentrations of the inorganic anion X-. The obtained curves were fitted with a single-exponential decay (y= y0 +A e- (xτ), k1ψ =1τ). The plot of the resulting k1ψ vs [X-] yields the values of the concentration-independent second-order rate constants as a slope of the straight lines.
