Consider the following reaction, taking place in a container fitted with a movable piston. 2SO2(g)+O2(g)→2SO3(g) Suppose we place two moles each of SO2 and O2 in the reaction vessel at 25∘C, and adjust the volume to give a total pressure of 1.0atm. The reaction is ignited by a spark, and goes to completion. The temperature is returned to 25∘C. Which of the following best describes this system after reaction is complete?
O2 is limiting. The volume of the system remains the same.
SO2 is limiting. The volume of the system remains the same.
Neither reactant is limiting. The volume of the system decreases.
SO2 is limiting. The volume of the system decreases.

Q2
A reaction system in equilibrium according to reaction : 2SO2(g)+O2(g)⇌2SO3(g) in one litre vessel at a given temperature was found to be 0.12 mole each of SO2 and SO3 and 5 mole of O2. In another vessel of one litre contains 32g of SO2 at the same temperature. What mass of O2 must be added to this vessel in order that at equilibrium 20% of SO2 is oxidised to SO3:
