Part A: Calculate the formation constant for the formation of [Cu(en)(H2O)4]2+ from [Cu(H2O)6]2+, given that ΔG° is -60.1kJ⋅mol-1 at 298 K.
Part B: Consider the formation of [Ni(en)3]2+ from [Ni(H2O)6]2+. The stepwise ΔG° values at 298 K are
ΔG°1 for first step=-42.9 kJ⋅mol-1
ΔG°2 for second step=-35.8 kJ⋅mol-1
ΔG°3 for third step=-24.3 kJ⋅mol-1
Calculate the overall formation constant (Kf) for the complex [Ni(en)3]2+.
Why is a solution of sodium bisulfite added to the reaction product mixture? Write a reaction to account for what is happening
For the subsequent reactions, look up the delta Hf values to compute delta H rxn and S values to evaluate delta S system and hence compute delta S universe at 298 K.
Betty, in a hurry to finish part 2 of the experiment, did not let the NaOH solution from part 1 cool at all. She just added it to the HCL solution and took the average temperature as the initial temperature of the mixture.
A 0.1651-g sample of an unknown monoprotic acid was dissolved in 28.4 mL of water and titrated with 0.0634 M NaOH solution. The volume of base required to bring the solution to the equivalence point was 19.1 mL. Calculate the molar mass of the aci..
2H2S (g) + 3O2 (g) → 2H2O (g) + 2SO2 (g) If 3.50 g of H2S are used in the above reaction, what will be the theoretical yield of water in grams.
A 32.22 g sample of a metal that looks like aluminum is heated to 99.8 C in hot water. The metal is then quickly transferred into exactly 50.0 ml of water at 22.9 C in a calorimeter
In the Bohr model of the atom, are the electron in shells closer to the nucleus higher of lower in energy than electrons in shells father for the nucleus
Hemoglobin has a mass of about 67,000 g/mol. It is 0.3335% iron by mass. How many iron atoms are in a molecule of hemoglobin?
Butadiene, C4H6 (used to make synthetic rubber and latex paints) changes into C8H12 with a rate law of rate = 0.014 L/(mol·s) [C4H6]2. What will be the concentration of C4H6 after 2.0 hours if the initial concentration is 0.025 M
Using the inverse square law of radiation, what Geiger counter reading would you get for a radioactive material when you are 3 feet from the source (assume an initial reading of 6300 R at a distance of 1 foot from the source)?
Calculate Keq at 25 degreeC and at 500 degree C. Make a statement like "for the haver process, the reaction is more/less product favored as the temperature goes up/down."
You place barium sulfate (BaSO_4) in water and it reaches equilibrium. Assuming that the concentration of SO_4^2- is raised to 6 M in the solution, what would the concentration of the Ba^2+ in solution be
