What molecular shape is SO3?

What molecular shape is SO3?

trigonal planar

What is the balanced equation for SO2 O2 SO3?

The balanced equation is 2SO2+O2→2SO3 .

Which crystal is used for converting SO2 into SO3 gas?

The purified sulphur dioxide is oxidised by oxygen at 400-600 degree celsius over a catalyst consisting of vanadium pentoxide with potassium oxide on a silica support.

Why h2so4 is not obtained by directly reacting SO3 with water?

Sulphuric acid is not obtained directly by reacting SO3 with water because the reaction is highly exothermic which produce the fine misty droplets of sulphuric acid that is not directly absorbed by water.

How is oleum formed from SO3 in this process?

Adding an excess of oxygen to sulfur dioxide in the presence of the catalyst vanadium pentoxide at 450 °C and 1-2 atm. The sulfur trioxide formed is added to sulfuric acid which gives rise to oleum (disulfuric acid) The oleum is then added to water to form sulfuric acid which is very concentrated.

Which catalyst is used in oxidation of SO2 to SO3?

Vanadium-based catalysts have well known uses in several reactions such as oxidative dehydration [1,2], oxidative dehydrogenation [3] and in the notable oxidation of sulfur dioxide to sulfur trioxide, a step in the production of sulfuric acid.

Is SO2 reducing agent?

Reactions. Featuring sulfur in the +4 oxidation state, sulfur dioxide is a reducing agent.

How does V2O5 Act catalyst?

V2O5 can act as catalyst as vanadium (V) is a transition metal and it has availability of vacant d-orbitals. Due to which vanadium can show variable oxidation states. Vanadium is able form unstable intermediate compounds.

Which catalyst is used for converting?

The catalyst used in the converter is mostly a precious metal such as platinum, palladium and rhodium. Platinum is used as a reduction catalyst and as an oxidation catalyst. Although platinum is a very active catalyst and widely used, it is very expensive and not suitable for all applications.
