Homework Help: Partial pressure question (should be easy)

  1. Dec 2, 2008 #1
    1. The problem statement, all variables and given/known data

    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?

    2. Relevant equations

    3. The attempt at a solution

    Assuming constant temperature and volume ; in the case there is no need to account for equilibrium you need to find the correct mole ratio by observing the stoichiometric equation.

    As it was already signalled you can't balance equation that have nitrogen on only one side.
