    \[\frac{\big[\text{NaCl}\big](t)}{\big[\text{NaCl}\big]_0} = e^{-t/\tau}\\ \ln\tfrac{\big[\text{NaCl}\big](t)}{\big[\text{NaCl}\big]_0} = -t/\tau\\ \tau\ln\tfrac{\big[\text{NaCl}\big]_0}{\big[\text{NaCl}\big](t)} = t\\\tau = \frac t{\ln\tfrac{\big[\text{NaCl}\big]_0}{\big[\text{NaCl}\big](t)}}\]
