Principle to predict the result of changing co.. Carbon disulfide and oxygen react to form carbon dioxide and sulfur dioxide, like this: CS2(g)+3O2(g) CO2(g)+2SO2(g) Suppose a mixture of CS,, O2, CO2 and SO, has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbati below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. change in composition shift in equilibriunm to the right O to the left (none) O to the right @ to the left The pressure of CS, will ? Some O2 is removed The pressure of Co, will ? The pressure of CS2 will Some SO, is added. The pressure of O, will ? | (none) to the right The volume of the vessel is The pressure of co, will ? reduced O to the left (none)Explanation / Answer
Since the reaction has reached to its equillibrium state , any change in the condition of reaction , will shift the equillibrium to either of the direction , so that the equillibrium can be re-estabilished. This is in accordance with the Le chatelier's principle.
So here :
Some O2 is removed :
The pressure of CS2 will increase
The pressure of CO2 will decrease
The equillibrium will shift to the left
Some SO2 is added :
The pressure of CS2 will increase
The pressure of O2 will increase
The equillibrium will shift to left.
The volume of the vessel is reduced :
The pressure of CO2 will increase
The pressure of SO2 will increase
The equillibrium will shift to right.
