To determine the effects of adding or removing materials on the equilibrium of the reaction 2SO₃⇌2SO₂+O₂, we can consider Le Chatelier's principle.
A) If we add SO₂ or O₂ to the reaction mixture, it will disrupt the equilibrium. According to Le Chatelier's principle, the system will try to counteract the change by shifting the equilibrium to the left to decrease the concentration of SO₂ and O₂. Thus, the answer is A) Shift left.
B) If we remove SO₂ or O₂ from the reaction mixture, it will also disrupt the equilibrium. The system will then try to counteract the change by shifting the equilibrium to the right to increase the concentration of SO₂ and O₂. So, the answer is B) Shift right.
C) If we add or remove an inert gas, such as nitrogen (N₂), it will not affect the equilibrium because inert gases do not participate in the reaction. Therefore, the answer is C) No shift.
D) Increasing the temperature of the reaction will favor the endothermic reaction (the reaction absorbing heat), according to Le Chatelier's principle. In this case, the forward reaction is endothermic, as indicated by the heat term in the reaction, and increasing the temperature will shift the equilibrium to the right to offset the increase in temperature. Thus, the answer is D) Shift right.
In summary, the answers are:
A) Shift left - if we add SO₂ or O₂.
B) Shift right - if we remove SO₂ or O₂.
C) No shift - if we add or remove an inert gas.
D) Shift right - if we increase the temperature.
