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...

ln(k) = -E_a/R 1/T + ln(A) A plot of ln (k)versus 1/T result in a straight line with a slope = -E_a/R. The value of E_a can then be calculated using the value of R and to the slope of the line. This experiment uses the Arrhenius equation, which relates the temperature and specific reaction rate constant to determine the activation energy for the crystal violet reaction. The reaction will be performed at different temperatures. Once the order of reaction...
