            A. [H2] decreases

            B. [CH4] increases

            C. The temperature increases

            D. All concentrations remain constant

2. Consider the following equilibrium: SO2Cl2(g) + energy ? SO2(g) + Cl2(g)

            When the temperature is decreased, the equilibrium shifts

            A.        Left and [ SO2Cl2 ] increases

            B.        Left and [ SO2Cl2 ] decreases

            C.        Right and [ SO2Cl2 ] increases

            D.        Right and [ SO2Cl2 ] increases

3. Consider the following reaction:

2SO2(g) + O2(g) ? 2SO3(g)     ?H = -197 kJ/mol

Which of the following will not shift the equilibrium to the right?

            A.        Adding more O2

            B.        Increasing the temperature

            C.        Increasing the pressure

            D.        Lowing the temperature

4. Consider the following equilibrium:

      2SO3(g) ? 2SO2(g) + O2(g)

The volume of the system is decreased at a constant temperature. A new state of equilibrium is established by a shift of the original equilibrium to the

            A. Left and [SO3] increases

            B. Right and [SO3] decreases

            C. Left and [SO3] remains unchanged

            D. Right and [SO3] remains unchanged

5. Consider the following equilibrium:

2SO2(g)   + O2(g)   ?   2SO3(g)      ?H = -198 kJ

There will be no shift in the equilibrium when

            A. More O2 is added

            B. Catalyst is added

            C. The volume is increased

            D. The temperature is increased
