Sulfur dioxide and oxygen react to form sulfur trioxide, like this: 2502(g)+O2(g

Question

Sulfur dioxide and oxygen react to form sulfur trioxide, like this: 2502(g)+O2(g) 2SO3(g) Suppose a mixture of SO,, O2 and SO, has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left. perturbation change in composition shift in equilibrium O to the right to the left The pressure of SO2 will? Some SO3 is added. The pressure of O2 w ? (none) O to the right The pressure of SO2 wll? to the left Some 02 is removed The pressure of SO3 will? none O to the right to the left The volume of the vessel is reduced The pressure of SO3 will? none

Explanation / Answer

Given reaction is - 2SO2(g) + O2(g) 2SO3(g)

--> when SO3 is added - reaction shift to the left. SO2 and O2 amount will increase so there pressure also increase.

--> when O2 is removed - the system will try to increase the amount O2. Therefore the equilibrium shifts to left. pressure of SO2 is increased as concentration increase whereas concentration of SO3 is decreased so its pressure also decreases.

--> volume f the vessel reduced - the equilibrium will shift towards the side of the reaction with fewer mole

so reaction shift towards the right.

So, the SO3 amount increased hence the pressure of SO3 also increases.
