Homework Help: Need help with equilibrium equations - Please

  1. Jul 29, 2013 #1
    Need help with equilibrium equations -- ASAP Please

    1. The problem statement, all variables and given/known data

    I'm studying for a final that I'm taking tomorrow and am stuck on the following:

    Calculate Kc for the reaction:

    4NOBr (g) [itex]\Leftrightarrow[/itex] 4NO (g) + 2Br2 (g)

    given the following information:

    2NO(g) + Br2 (g) [itex]\Leftrightarrow[/itex] 2NOBr (g); K = 2.0

    2. Relevant equations

    Not sure about which equations other than Kc = [itex]\frac{[products]}{[reactions]}[/itex]

    3. The attempt at a solution

    I can't even start this answer. My first assumption of where to start was to write the second equation backwards, just so it looked like the first!!??
