Given the following gaseous reaction at equilibrium: 2 SO2(g) + O2(g) ⇌ 2 SO3(g), what effect would be noted on the concentration of SO2(g) when each of the following is done: (use I = Increase, D = Decrease; N.C. = No Change)
a. The equilibrium mixture is heated.
b. Some SO2(g) is removed from the equilibrium mixture.
c. The pressure of the system is increased.
d. More O2(g) is added to the vessel.
e. The temperature is lowered.
