Partial Pressure question (should be easy to answer)

Click For Summary
SUMMARY

The discussion centers on the concept of partial pressures in the context of the reaction H2 + 2O2 = 2HNO2. Given the partial pressures of H2 at 0.5 and O2 at 0.3, it is established that the partial pressure of the product, 2HNO2, cannot be 0.8 due to the constraints of Dalton's Law of Partial Pressures. The total partial pressures of gases in a container must not exceed the total pressure, which is a fundamental principle in gas behavior.

PREREQUISITES
  • Understanding of Dalton's Law of Partial Pressures

Homework Statement



if you have an equation such as H2+2O2=2HNO2 and you know the partial pressure of H2 is .5 and the partial pressure of O2 is .3, does that mean that the partial pressure of 2HNO2 is .8?

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
If the partial pressures are expressed as fractions of the total pressure, then the sum cannot be more than 1. You have all gasses in the same container, right? Both reactants and products. So the product cannot have 0.8 if you already have 0.5 and 0.3.
But first you need to answer the question asked by LowlyPion, anyway.
