Write the chemical equation for the formation of ozone.

Click For Summary

Discussion Overview

The discussion revolves around the chemical equation for the formation of ozone from molecular oxygen, including related concepts such as entropy change, stability of ozone, and the effects of temperature on its stability. The scope includes homework-related inquiries and theoretical considerations.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant states that ozone can be prepared from molecular oxygen by electrical discharge and mentions the standard free energy of formation of ozone as +163.4 kJ/mol.
  • Another participant questions the possibility of writing a chemical equation for the formation of ozone and expresses uncertainty about their understanding of the topic.
  • One proposed equation for the formation of ozone is O2 + O = O3, although this is met with skepticism regarding the role of atomic oxygen.
  • There is a suggestion that the entropy change for the reaction would be positive, based on the overall reaction being positive.
  • A participant expresses the belief that ozone would become less stable as temperature increases, suggesting that added heat destabilizes the particles involved.
  • Another participant emphasizes the importance of balancing the chemical equation and maintaining the same number of atoms on both sides, reiterating the need for clarity on the chemical symbols for oxygen gas and ozone gas.
  • One participant challenges the initial equation by suggesting that atomic oxygen may not be relevant and prompts consideration of different amounts of diatomic oxygen and ozone, along with the entropic implications of gas formation or destruction.

Areas of Agreement / Disagreement

Participants express differing views on the correct chemical equation for the formation of ozone, the role of atomic oxygen, and the implications of entropy and temperature on ozone stability. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are uncertainties regarding the assumptions made about the role of atomic oxygen in the reaction and the implications of entropy changes. Participants have not reached a consensus on the correct chemical equation or the stability of ozone under varying temperatures.

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?
