Question

Consider this equilibrium: COCl2(g) CO(g) + Cl2(g) Keq = 8.1 x 10-4. What is true for this system? [COCl2] < [CO][Cl2] [COCl2] = [CO][Cl2] [COCl2] > [CO][Cl2]

2 Answer

  • I'm pretty sure the answer here is C.
  • Answer is: [COCl₂] > [CO][Cl₂].

    Chemical reaction: COCl₂(g) ⇄ CO(g) + Cl₂(g); Keq = 8.1 x 10⁻⁴.

    Keq = [CO] · [Cl₂] / [COCl₂]; equilibrrium constant of chemical reaction.

    [CO] · [Cl₂] / [COCl₂] = 0.00081.

    Equilibrium product concentration is much more less than equilibrium concentration of reactant.
