The Anderson–Newns–Grimley model allows the energy of this process to be calculated in a self-consistent manner by introducing another term to the Hamiltonian. It’s not distillation, but azeotropy in this process can be described using a DSL model. Reaction kinetic models for heterogeneous catalysis contain constants for this process in the denominator, which use an isothermal mechanism for this process (10[1])named for Langmuir. BET isotherms for this process account for multilayer interactions. Activated carbon and zeolites are two examples of surfaces where this process commonly occurs. For 10 points, name this process in which atoms bond to a surface, such as when gas (10[1])molecules attach to solid substrates. ■END■ (0[2])
