I will have a quiz also for the same topic if you can do this homework correct then I will work with you for the quiz.

Thanks you

1)

Define:

  • Entropy
  • Spontaneous / Nonspontaneous processes
  • Gibbs Free Energy
  • 2nd Law of Thermodynamics

2)

Calculate ΔS298 for the following changes.

Cu(s)⟶Cu(g)

3)

Calculate ΔS298 for the following changes. You may be given a reaction by using the names. For example this reaction would be, “Solid zinc reacts with copper(II) sulfate to produce solid copper and zinc sulfate”

Zn(s)+CuSO4(s)⟶Cu(s)+ZnSO4(s)

4)

N2O4(g) → 2NO2(g)

Calculate the following information. Copy and paste this in your answer below to be clear what you are reporting. Include your units with your answer.

  1. ΔG298
  2. ΔH298
  3. ΔS298
  4. Is this reaction spontaneous at 298K?
  5. What temperature would make this reaction change the answer to (4)?
  6. What is the ΔG value at 425K?

5)

Use the standard free energy of formation data in Standard Thermodynamic Properties for Selected Substances to determine the free energy change for each of the following reactions, which are run under standard state conditions and 25 °C.

CS2(g)+3Cl2(g)⟶CCl4(g)+S2Cl2(g)

6)

Calculate ΔGrxn for the following:
CaCO3 (s) → CaO(s) + CO2 (g)

Given:

Ca(s) + CO2 (g) + 1/2 O2 (g) → CaCO3 (s) ΔGrxn=-734.4 kJ

2 Ca(s) + O2 (g) → 2CaO (s) ΔGrxn=-1206.6 kJ
