    At 1495 degrees Celcius Kc for H2 + Br2 > 2HBR = 3 x 10 to the 4th power.

    H2 = .10 M
    Br2 = .20M

    What eqation(s)would I use or steps would I take to find the concentration of HBr?

    SOLUTION This solution is FREE courtesy of BrainMass!

    For a reaction of the type, aA + bB -->cC + dD

    We have, Kc = {[C]^c * [D]^d }/[A]^a * [B]^b

    where [A] is the conc. of A and so on

    Here Kc = [HBr]^2/[H2]* [Br2]

    therefore [HBr] = sqrt {Kc * [H2]*[Br2]}

    = sqrt {3*10^4 * 0.1*0.2}

    = 24.49 M
