arrhenius model to inspect the composition dependence viscosities of binary systems involving ionic liquids

many viscosity datasets for binary systems analyzed with the arrhenius model to inspect the composition dependence of the arrhenius fit parameters activation energy, e_a, and y-intercept, lna. the majority of the binary systems show linear dependence of ea and lna with mole fraction, either over the entire range of composition or over a wide range of compositions, typically between 0.2 < xil< 1.0. these findings are useful for estimating unknown viscosities for binary systems involving ils.
