Answer 2

The chemical reactions you've listed appear to involve the conversion of sulfur dioxide (SO2) to sulfuric acid (H2SO4) via the formation of sulfur trioxide (SO3) and subsequent reactions with sodium hydroxide (NaOH) to produce sodium sulfate (Na2SO4). Let's break down each step of the reactions:

1. SO2 → SO3: In this step, sulfur dioxide (SO2) is oxidized to sulfur trioxide (SO3). This reaction typically involves the use of a catalyst and elevated temperatures:

   2 SO2 + O2 → 2 SO3

2. SO3 → H2SO4: Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4) through a highly exothermic reaction known as the contact process:

   SO3 + H2O → H2SO4

3. H2SO4 → Na2SO4: Sulfuric acid (H2SO4) can react with sodium hydroxide (NaOH) to produce sodium sulfate (Na2SO4) and water (H2O):

   H2SO4 + 2 NaOH → Na2SO4 + 2 H2O

So, in summary, the reactions you've provided describe the conversion of sulfur dioxide (SO2) into sodium sulfate (Na2SO4) through the intermediate formation of sulfur trioxide (SO3) and sulfuric acid (H2SO4). These reactions are fundamental in industrial processes, such as the production of sulfuric acid and sodium sulfate.
