# Multi Component Bi-Langmuir LDFΒΆ

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

\[\begin{aligned}
q_{i,j}^*=\frac{q_{m,i,j} k_{eq,i,j} c_i}{1 + \sum_{k=1}^{N_{comp}}{k_{eq,k,j} c_k}} && i = 0, \dots, N_{\text{comp}} - 1, \: j = 0, \dots, M - 1.% (0 \leq i \leq N_{\text{comp}} - 1, \: 0 \leq j \leq M - 1).
\end{aligned}\]
