Answer #1

The following problem can be solved using the Le Chatelier's principle which states that whenever a system in equilibrium is disturbed, the system proceeds in such a direction so as to reverse the effect of the disturbance.

In the given question, number of gaseous moles is more on the reactant side.

Therefore, due to an increase in volume, that is, a decrease in pressure of the reaction, the reaction proceeds according to Le Chateliers so as to increase the pressure, by increasing the number of gaseous molecules, which is in fact, the reverse reaction.

In the reverse reaction, SO3 is used up, leading to a decrease in the production of SO3.

Therefore, the correct answer is A) Increase in volume
