Equilibrium constant problem

  1. Oct 25, 2013 #1
    1. The problem statement, all variables and given/known data

    H2+CO2=CO+H2O
    if 1.50 mol of each chemical species are placed in a 3.00l flask and allowed to achieve the equilibrium above, what mass of Co will be present at equilibrium?

    2. Relevant equations

    Keq= concentration of products each raised to the number of moles in equation/ concentration of reactants raised to the number of mols

    3. The attempt at a solution
    I used the ice tables and substituted the variables then used the equilibrium constant equation to determine x

    My answer came out to be 55 g but the answer on the worksheet said 13.0 g. I think the answer on the worksheet is wrong, because I double checked my answer and still didn't get it? Just wondering for a 2nd opinion from someone

    Sigh. What is the value of the constant?

    The value of the constant is 3.59

    Your answer seems right. With that equilibrium constant, you would expect to end up with more than 1.5 moles of CO, rather than less.

    Ok thanks, I think the answer on the sheet is wrong
