The rate of a chemical reaction is defined as the quantity of product formed in unit time. In this context, quantity may mean either weight, volume, or number of particles of product per unit volume. The reaction rate is dependent on the availability of reactant and the energy barrier involved in the bond redistribution processes necessary to complete the chemical transformation. Reaction rates are thus dependent on many variables, including (inter alia) temperature, pressure, concentration (availability and mobility) of participating elements (ionic species), deformation (which may exert a significant effect on diffusion rate), catalyst (both homogeneous and heterogeneous), and the ease of nucleation and growth of the product.
A major objective of metamorphic petrology is to provide a mechanistic description of the changes that occur during metamorphism. While the role of equilibrium in such transformations has been considered at length by the methods of thermodynamics, the...
