Chemistry · Chemical Kinetics
In the reaction between two ions, the rate constant is k r when the ionic strength (I) is 0.004. The rate constant is k r 0 when the activity coefficient is 1. The ratio k r /k r 0 = 0.884. If the charge of one ion is +1, the charge of the other ion is close to: (Debye-Hückel constant = 0.509 at 298 K; log 0.884 = -0.05)
