What is the practical distinction between proportional and linear? Consider the difference between Henry's law, \(y_{B}=\frac{H_{B}}{p_{\text {tot }}} x_{B}\), and the general expression for linear equilibrium, \(y_{B}=\mathrm{mx}_{B}+b\) with \(b eq 0\). If \(\mathrm{x}_{\mathrm{B}}\) is doubled, does \(\mathrm{y}_{\mathrm{B}}\) double in both cases?
