Figure 1.

Comparison of the contributions of the linear (■) and quadratic (□) concentration terms in the expression for $\ln \left(z_{\text{A}}/\overline{C}\right)$ with $\overline{C}$ = 0.1 mM and a range of dimerization constants. Data are calculated from Eq. 8 with B_AA = 450 L mol⁻¹, B_AP = 1300 L mol⁻¹, and B_AAA = 127,300 L² mol⁻² (see text).
