QuestionAnswer
what is added to sulphur trioxide to make sulphuric acidwater, this reaction is not reversible
what is sulfur used to manufactor in the contact processsulphuric acid, for this reaction : sulphur, air and water in needed
what do we do with the sulphur firstburned to the air
what happens when the sulphur burned in the airreacts with oxygen to make sulphur dioxide. Sulphur dioxide is highly dangerous as it contributes to acid rain
symbol equation of reaction of sulphur and oxygenThis reaction is not reversible. S + O2 → SO2
factors of the contact process450 degrees
factors of the contact prcoess2 atmospheres
factors of the contact processvanadium catalyst
after sulphur + oxygen reaction, what is the next reactionsulphur dioxide reacts with oxygen to make sulphur trioxide. This reaction is reversible. 2SO2 + O2 ⇌ 2SO3
what is added to sulphur trioxide to make sulphuric acidwater, this reaction is not reversible
why is the addition of water to sulphur trioxide badhighly dangerous and exothermic as it forms clouds of hazardous sulphuric acid
how do we fix the dangers of adding water to sulphur trioxidesulphur trioxide is added to concentrated sulphuric acid to make oleum (H₂S₂O₇), which is then reacted with water to make sulphuric acid again. SO3 + H2SO₄ → H₂S₂O₇ then H₂S₂O₇ + H2O → 2H2SO₄
