    2NH3(g) ⇌ N2(g) + 3H2(g)
    For the above reaction at equilibrium the concentrations are as follows:
    [NH3]eq = 0.010M
    [N2]eq = 0.050M
    [H22]eq = 0.0010M
    What is the value of the equilibrium constant (Kc) for the reaction?

    H2(g) + Cl2(g) ⇌ 2HCl(g)            Kc = 16
    If 2 moles of both H2 and Cl2 are each placed in a 2L vessel, what will be the equilibrium concentrations of H2, Cl2, and HCl?

    HCN(aq) ⇌ H+(aq) + CN-(aq)            Kc = 4.9 × 10-10
    0.1 moles of HCN are added to a liter of solution. What is the equilibrium concentration of H+ in the solution?
