Consider the reaction 2 SO2(g) + O2(g) <===> 2 SO3(g) where /_\Hrxn = 198 kJ. The amount of SO2(g) at equilibrium increases when 1. the temperature is decreased. 2. SO3 is removed. 3. the volume is increased. 4. the pressure is increased. 5. more oxygen is added.

The equilibrium constant Kc for the reaction 2 SO2(g) + O2(g) ---> 2 SO3(g) is 11.7 at 1100 K. A mixture of SO2, O2, and SO3, each with a concentration of 0.015 M, was introduced into a container at 1100 K. Which of the following is true? 1. SO3(g) will be formed until equilibrium...
