    9)  What is the symbolic expression for the equilibrium constant for the reaction:
    2 C2H6(g) + 7 O2(g) 4 CO2(g) + 6 H2O(g)?

    10)  What is the gas phase chemical reaction that corresponds to the equilibrium constant expression shown below?

    11)  Consider the reaction: N2(g) + O2(g) 2 NO(g). If [N2] = 0.520 M, [O2] = 0.0662 M, and [NO] = 0.00956 at equilibrium, calculate the value of K and describe the physical/chemical interpretation of this K value.
