    Chemical energy is released or absorbed from reactions in various forms. The most easily measurable form of energy comes in the form of heat, or enthalpy. The enthalpy of a reaction can be calculated from the heats of formation of the substances involved in the reaction: ΔH∘rxn=ΔH∘f(products)−ΔH∘f(reactants) Entropy change, ΔS∘, is a measure of the number of energetically equivalent microstates introduced into the system during the reaction. The degree of spontaneity of a reaction is represented by the Gibbs free...

    Borax, sodium tetraboratedecahydrate, is an important mineral found in dry lakebeds in California. It is used to make soap and glass and used as a preservative. You can use the values of Ksp (solubility-product constant) of borax at different temperatures to determine ΔH∘, ΔS∘, and ΔG∘ for the dissolution of borax: Na2B4O5(OH)4⋅8H2O(s)(borax)→2Na+(aq)+B4O5(OH)42−(aq)(tetraborate)+8H2O(l) The relationship ln(Ksp)=−ΔH∘RT+ΔS∘R has the form of a linear equation, y=mx+b, where y is lnKsp and x is 1/T. The slope (m) is equal to −ΔH∘/R, and the...
