Calculate the standard change in Gibbs free energy, ΔG°rxn, for the following reaction at 25.0 °C. Standard Gibbs free energy of formation values can be found here.
KCl (s) (double arrow) K+ (aq) + Cl- (aq)
Delta Gorxn = - 6.2 kj/mol
Then, determine the concentration of K (aq) if the change in Gibbs free energy, ΔGrxn, for the reaction is -8.27 kJ/mol. What is [K+] ? Answer must be in M.
This portion is dissolved in acidic media before diluting to 250.0mL in distilled water. from this you take a 1.00mL aliquot and dilute this to 200.0mL in distilled water.
By titration, a water sample which was diluted tenfold had an initial DO of 9.3 mg/L, a final DO of 3.35 mg/L, an initial dilution water DO of 8.32 mg/L and a final dilution water DO of 10.33 mg/L.
