Chapter 15: Problem 103

The volume of the reaction vessel containing an equilibrium mixture in the reaction \(\mathrm{SO}_{2} \mathrm{Cl}_{2}(\mathrm{g}) \rightleftharpoons\) \(\mathrm{SO}_{2}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g})\) is increased. When equilibrium is re-established, (a) the amount of \(\mathrm{Cl}_{2}\) will have increased; (b) the amount of \(\mathrm{SO}_{2}\) will have decreased; (c) the amounts of \(\mathrm{SO}_{2}\) and \(\mathrm{Cl}_{2}\) will have remained the same; (d) the amount of \(\mathrm{SO}_{2} \mathrm{Cl}_{2}\) will have increased.

Short Answer

Expert verified
(a) The amount of Cl2 will have increased. (b) Incorrect, the amount of SO2 will have increased. (c) Incorrect, the amounts of SO2 and Cl2 will have increased. (d) Incorrect, the amount of SO2Cl2 will have decreased.

Step by step solution

01

Identifying The Reaction Direction

In the given reaction, \(\mathrm{SO}_{2} \mathrm{Cl}_{2}(\mathrm{g}) \rightleftharpoons \mathrm{SO}_{2}(\mathrm{g})+\mathrm{Cl}_{2}(\mathrm{g})\), the number of moles of gas on the products side (SO2 and Cl2) is more than the reactants side (SO2Cl2). So, when the volume of the reaction vessel increases, the reaction will proceed in the forward direction to increase the number of moles of gas and thus, counteract the change.
02

Changes in the amounts of the gases

Now, as the reaction proceeds in the forward direction, the amount of SO2Cl2 which is the reactant will decrease. As a result, the amount of both Cl2 and SO2 will increase as they are the products of the forward reaction. This is in accordance with Le Chatelier's principle as it occurs to counteract the increase in volume and decrease in the pressure of the system.
03

Conclusion for each statement

On analyzing the scenario, (a) the amount of Cl2 will have increased, which is correct. (b) The amount of SO2 will have decreased, which is incorrect as the amount of SO2 will have increased. (c) The amounts of SO2 and Cl2 will have remained the same, which is incorrect as both will have increased. (d) The amount of SO2Cl2 will have increased. This statement is also incorrect as the amount of SO2Cl2 will have decreased.
