Confused by an exercise on the subject of chemical equilibrium

Click For Summary

Discussion Overview

The discussion revolves around a confusion regarding an exercise related to gas reactions and their concentrations within the context of chemical equilibrium. Participants explore concepts relevant to the problem set from a course titled "introduction to chemical equilibrium."

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • One participant expresses confusion about the exercise, indicating that their questions depend on the responses received.
  • Another participant introduces the concept of "fugacity," questioning the original poster's familiarity with it.
  • The original poster clarifies that "fugacity" is not mentioned in the exercise, suggesting a focus on more basic concepts.
  • A participant explains that the concentration of a gas in a mixture can be understood similarly to general concentration, noting the relationship between moles and volume, and mentions the possibility of interconverting with partial pressure.
  • A later reply asks about the starting pressure in relation to the ideal gas law, implying a need for foundational information to address the exercise.

Areas of Agreement / Disagreement

The discussion does not present a consensus, as participants are exploring different concepts and clarifications without agreeing on a specific approach or solution to the exercise.

Contextual Notes

Participants have not established the assumptions or definitions necessary for a complete understanding of the exercise, and the relevance of "fugacity" remains unclear in this context.

Homework Statement
I assume that they talk about partial pressure and calculate it instead of the concentration .
Relevant Equations

Hello , i am a little confused about this exercise because we talk about gases reaction and we are asked about the concentrations
P.S : i have other questions that depends on your answer .
Thanks .

Are you familiar with the concept of "fugacity?"
 
no,this exercise is from the problem set of a course called "introduction to chemical equilibrium " and the concept of "fugacity" is not mentioned .

Concentration of a gas in a mixture is not much different from a concentration in general - just number of moles in a volume. Can be reasonably easily interconverted with the partial pressure.
 
From the ideal gas law, what is the starting pressure?
