The dictionary defines stress as the "bodily or mental tension resulting from factors that tend to alter an existent equilibrium." Your thoughts become unbalanced. In the absence of chemical mass transport, mineral-hydration reactions would be accompanied by a solid-volume increase that may induce differential stresses and associated reaction-induced deformation processes, such as dilatant fracturing to increase fluid permeability. Add your answer and earn points. The affinity term I A P j / K e q, j quantifies the distance of solution from the equilibrium state of the mineral reaction j. Minerals that are opaque and shiny, such as pyrite, have a metallic luster. Here we show that the simplest hydration reaction in nature MgO + H2O Mg (OH)2 can induce stresses of several hundred megapascals, with local stresses up to 1.5 GPa.
