    1. For the reaction N2 + O2 → 2NO, Kc = 4.08 x 10-4 at 2000K. What is Kc at this same temperature for the reaction, NO → 1/2 O2 + 1/2 N2

    2. What is the total pressure of the gases above the carbon for the reaction C + CO2 → 2CO when the pressure of CO is ten times the pressure of CO2? The equilibrium constant, Kp = 63.

    3. Calculate the value of Kc for the reaction Ag+(aq) + Cl-(aq) → AgCl(s) if the concentrations at equilibrium are [Ag+] = 10-8M, [Cl-] = 0.01M.

    Please see the attached file for complete solution. Below is an incomplete copy of what's in the file:

    1. For the reaction N2 + O2 → 2NO, Kc = 4.08 x 10-4 at 2000K. What is Kc at this same temperature for the reaction, NO → 1/2 O2 + 1/2 N2

    For the reaction:
    N2 + O2 → 2NO
    We have

    NO → 1/2 O2 + 1/2 N2

    For the above reaction we have:

    2. What is the total pressure of the gases above the carbon for the reaction C + CO2 → 2CO when the pressure of CO is ten times the pressure of CO2? The equilibrium constant, Kp = 63.

    C + CO2 → 2CO
    We are given pCO = 10pCO2
    We can write the Kp as:
    = 63
    Thus pCO2 = 63/100 = 0.63 (pressure unit)
    The total gas pressure for the reaction is = pCO2 + pCO = 0.63 + 6.3 = 6.93 (pressure unit)

    3. Calculate the value of Kc for the reaction Ag+(aq) + Cl-(aq) → AgCl(s) if the concentrations at equilibrium are [Ag+] = 10-8M, [Cl-] = 0.01M.

    Ag+(aq) + Cl-(aq) → AgCl(s)
