Physics

Main article: Mixture § Physics_and_chemistry

chemistry

In chemical kinetics, a heterogeneous reaction is one that takes place at the interface of two or more phases, i.e. between a solid and a gas, a liquid and a gas, or a solid and a liquid. In heterogeneous catalysis the catalyst is in a different phase from the substrate. the state of constant fluctuation
