WebJan 30, 2024 · Step 1: Make sulfur dioxide. Step 2: Convert sulfur dioxide into sulfur trioxide (the reversible reaction at the heart of the process) Step 3: Convert sulfur trioxide into concentrated sulfuric acid. WebThe contact process has three main steps. The first of these steps is to make sulphur dioxide, SO₂. The second step is a reversible reaction where SO₂ is converted to SO₃, sulphur trioxide. In the final step, SO₃, sulphur trioxide, is converted into sulphuric acid. This question is asking us specifically about one of these three steps. alita lithiumWebanswer 3 ( b ) (I) Add To Classified 1 Mark The Contact process is usually carried out at a temperature of approximately 700 K, a pressure of approximately 150 kPa and in the presence of a vanadium (V) oxide catalyst, V2O5.
