When we cover particle dispersion using polymers I can use a kush ball or similar ball to give them a visual of what it will look like.
I provide a table with delta G, delta H and S values as well as the equations, Gibb's Free Energy: delta G = delta H - T delta S, and Boltzmann's Equation S=Kb ln(omega). Following are some calculations I have the students do. I may be over simplifying some of this.
6. A theoretical chemist determines that each of a certain type of molecule can potentially have 6 states like a six sided die. What is the probability, Ω, for 20 of these molecules?
7. A theoretical chemist determines that each of a certain type of molecule can potentially have 6 states like a six sided die. Use Boltzmann’s equation to calculate S for 1 mole of these molecules.
Hint: ln(6n) = n ln(6) and 1 mole = 6.022 x 10^23
8. A theoretical chemist determines calculates S before a reaction to be 14.9 J/mol/K. Convert this to cal/mol/K.
9. The reactants in a chemical reaction have an entropy of Sreactants = 3.56 cal/mol/K and the products in a chemical reaction have an entropy of Sproducts = 16.72 cal/mol/K. Calculate ΔS. Hint ΔS = Sproducts – Sreactants.
10. The heat generated by the reaction, ΔH is -57.8 kcal/mol. Use the free energy equation to calculate ΔG at room temperature.
