Oxidation of sulfur dioxide into sulfur trioxide in the absence of a catalyst is a slow process but this oxidation occurs easily in the atmosphere. Explain how does this happen.

Question

Oxidation of sulfur dioxide into sulfur trioxide in the absence of a catalyst is a slow process but this oxidation occurs easily in the atmosphere. Explain how does this happen., The atmosphere contains a high concentration of sulfur dioxide, which speeds up the oxidation process., Sulfur dioxide undergoes auto-catalysis in the atmosphere, accelerating its own oxidation., Atmospheric oxygen and moisture act as natural catalysts, promoting the oxidation of sulfur dioxide., Atmospheric pressure increases the rate of oxidation of sulfur dioxide.

MARKS App · Accepted Answer

Correct Option is : (C) Atmospheric oxygen and moisture act as natural catalysts, promoting the oxidation of sulfur dioxide.
