Representing the Rate of Production?

  1. Mar 25, 2015 #1
    1. The problem statement, all variables and given/known data

    Nitric oxide and oxygen gases react to form nitrogen dioxide gas in the reaction 2NO + O2 -> 2NO2

    Write a mathematical expression to represent the rate of production of nitrogen dioxide: 4.0x10-3mol/(L*s)

    2. Relevant equations

    r=k[X]m[Y]n

    3. The attempt at a solution

    Not really sure where to start off.

    Maybe you don't understand what the question is - nor do we - is this verbatim and from where?

    Maybe all they want is d[NO2]/dt = - d[NO]/dt = -½ d[O2]/dt = 4.0 X 10-3

    which you did not write because it was too obvious? :oldbiggrin:

    I would argue even just [itex]r=4.0 \times 10^{-3} \frac {mol}{L \times s}[/itex] qualifies as a correct answer :rolleyes:

    Yes but sometimes it is just as well to show off a bit. :oldbiggrin:
