The numbers in the parentheses indicate the phases in which the reactants and the products are soluble. Since X does not dissolve in phase 2 and Y in phase 1, their only possible meeting place is the interface between the two phases, 1 and 2. It is necessary to transport atoms of X and of Y to the interface. The reaction product XY has also to be transported away from the interface. The reaction would otherwise come to a halt due to the accumulation of XY at the interface. Each of these individual processes mentioned may be addressed as kinetic steps and for the reaction cited, these steps are (a) the transfer of X from the bulk of phase 1 to the interface (b) the transfer of Y from the bulk of phase 2 to the interface (c) chemical reaction at the interface and (d) the transfer of XY from the interface into the bulk of phase 1 (say). The steps listed can be grouped into two categories. The steps (a), (b), and (d) are mass transfer processes, while the step (c) is a chemical reaction step. A simpler situation is encountered in many of the reactions in process metallurgy. Phase 1 is a gas... 

Calcination is a widely used unit operation in process metallurgy, and the compound represented as solid 1 is usually a carbonate and solid 2, an oxide. The decomposition of hydroxides, besides being termed as drying as indicated in the previous section, is also called calcination.
