# Multi Component Langmuir LDFΒΆ

This a linear driving force model variant of the Multi Component Langmuir model. It is based on the equilibrium concentration \(q^*\) for a given liquid phase concentration \(c\) (see also Linear Driving Force (LDF)).

\[\begin{aligned}
q_i^*=\frac{q_{m,i} k_{eq,i} c_i}{1 + \sum_{j=1}^{n_{comp}}{k_{eq,j} c_j}} && i = 0, \dots, N_{\text{comp}} - 1.
\end{aligned}\]
