(b) The reaction between oxygen and sulphur dioxide: 2 S O 2 + O 2 ⇌ 2 S O 3 (c) There are 3 molecules on the reactant side and 2 molecules on the product side. So, the increase in the pressure of the system will favour the forward reaction. That means more products will be formed.

Sulfur Dioxide (SO2) |

Sulfur dioxide is a gas that enters the atmosphere as a result of burning fossil fuels and from volcanic eruptions. In the atmosphere, sulfur dioxide reacts with water vapor, oxygen, and nitrogen oxides to create acid rain. When rain is acidic, it causes considerable damage to forests and to the ecosystems of freshwater bodies.

What is the percentage of oxygen in sulphur dioxide? - Quora

Molecular formula for sulphur dioxide is So2. Atomic mass of sulphur is 32. Similarly atomic mass of oxygen is 16. But due to the presence of two oxygen atoms the total atomic mass become 2*16=32. Hence total atomic mass is 32+32=64. So the percentage of oxygen in sulphur dioxide is (32/64)*100=50%. Mike Jones
