- Homework Statement
- My teacher asked us to create an extremely difficult question that involves Gibbs free energy and/or isomers.
- Relevant Equations
- G=H-TS
I was thinking about giving the bond energy to calculate the enthalpy change of some exothermic and spontaneous reaction. Than using that exothermic enthalpy to heat the own products and reagents. That would change the Gibbs free energy of the equation (as the elements will be in a different temperature). That way the equilibrium constant will also change. Than I can say that if I put x moles of the reagent, how much product will be formed? Or how much reagent will still left?
For that it would be needed to calculate the new Gibbs free energy change and to extrapolate the enthalpy and entropy to that temperature. For the first one we could use n Cp delta(T), but I don’t know how to extrapolate the second. Also, it would be nice to put some isomers into the question, I don’t know.
Feel free to give some opinions. How could I get all of that together into a well structred question? Any other topic that you think it would be nice to put there? Or even some totally different question. It does not worth anything, it’s just for the class and the teacher try to solve difficult questions in the class and prepare for the test.
