Question

So2+02=s03 (катализатор V205)

Answer 1

Нужно уровнять? Тогда:

2SO2 + O2 = 2SO3

Answer 2

The chemical equation you provided is a representation of the reaction between sulfur dioxide (SO2) and oxygen (O2) to form sulfur trioxide (SO3) in the presence of the catalyst vanadium(V) oxide (V2O5):

2 SO2 + O2 → 2 SO3 (catalyst: V2O5)

This reaction represents the industrial process known as the Contact Process, which is used to produce sulfur trioxide on a large scale. The vanadium(V) oxide acts as a catalyst, meaning it facilitates the reaction without being consumed in the process. The production of sulfur trioxide is an important step in the manufacturing of sulfuric acid (H2SO4), a widely used industrial chemical.
