SUMMARY

The chemical equation for the formation of ozone (O3) from molecular oxygen (O2) is represented as 3 O2 → 2 O3. The standard free energy of formation for ozone is +163.4 kJ/mol, indicating that the reaction is endergonic. The entropy change for this reaction is positive, as the formation of ozone from oxygen increases the number of gas molecules, leading to greater disorder. As temperature increases, ozone stability decreases due to the added thermal energy destabilizing the molecular structure.

PREREQUISITES
  • Understanding of chemical thermodynamics, specifically Gibbs free energy.
  • Familiarity with chemical equations and stoichiometry.
  • Knowledge of entropy and its implications in chemical reactions.
  • Basic principles of gas behavior and stability.
NEXT STEPS
  • Study the principles of Gibbs free energy and its role in chemical reactions.
  • Learn about the entropic implications of gas formation and decomposition.
  • Research the stability of ozone and its environmental impacts.
  • Explore the methods of generating ozone, including electrical discharge techniques.
USEFUL FOR

Chemistry students, educators, and professionals interested in thermodynamics, ozone formation, and environmental chemistry.

Homework Statement


Ozone can be prepared from molecular oxygen by subjecting oxygen to an electrical discharge. The standard free energy of formation of ozone is +163.4kJ/mol.
a) write the chemical equation for the formation of ozone.
b) what sign of the entropy change for this reaction? justify your answer.
c) comment on the stability of ozone based on these data
d) as temperature increases, would you expect ozone to become more or less stable? justify your answer.

-should the possible equations be delta G system(free energy change)= delta H ( change in enthalpy) - T(temp.) System (represent the change in entropy
- q= c x m x deltaT

The Attempt at a Solution


a) the chemical equation is... ? is it really possible to make an equation of ozone and oxygen to create a 163.4kJ/mol ??
b) the entropy reaction would be a positive because of the reaction total is a positive.
c)?
d) as temperature increases, I would expect ozone to become less stable because if temperature is added more heat making the the other particles unstable that's combined to it


I don't know if I'm right or even know what I'm doing..please can someone help me.

A chemical equation has the chemical symbols of the reactants on one side and the products on the other. The number of atoms of each element is the same on each side. What are the chemical symbols for oxygen gas and ozone gas?
 


would it be O2 + O = O3

Not quite; atomic oxygen probably doesn't participate (in the context of this homework problem). How about combining different amounts of diatomic oxygen and ozone? What are the entropic implications of creating or destroying a mole of gas?
