![3) The dissociation of ammonium nitrate in aqueous solutions is described by the following chemical reaction Use the information provided in the table below at 25°C, to plot the Gibbs free energy change as a function of the natural logarithm of Q, InQ. [Recall that Q is the quotient of the product of the products raised to the stoichiometric coefficients over the product of the reactants raised to their stoichiometric coefficients.] a) On the ΔG vs In(Q) plot indicate the equilibrium and standard state values of the Gibb s free energy change. b) Replot ΔG vs In(Q) at 50°C and comment on the observed changes. Will be the thermodynamics of the reaction be in general more or less favorable at this temperature?

The general form of a chemical reaction is aA + bB = cC +dD Where A and B are reactants in the forward direction and C and D are products in the forward direction. The lower case letters are the stoichiometric coefficients for the balanced equation. The general form of the equilibrium constant equation is then: Keq = [C]c[D]d/[A]a[B]b Part I: Q vs. K Q: reaction quotient can be calculated for a reaction at any concentration values of reactants and...

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...
