Jan 18, 2025 · Revision notes on The Contact Process for the Cambridge (CIE) O Level Chemistry syllabus, written by the Chemistry experts at Save My Exams.

Stages of the contact process: • When a spray of molten sulfur is burned in a blast furnace in a current of dry air, sulfur dioxide is formed. Reaction: S(g) + O2(g)----> SO2(g) Note: Molten …

In the Contact process, the vanadium (V) oxide (V2O5) catalyst increases the rate of reaction - but it does not change the position of equilibrium. The position of equilibrium is already on the …

A description of the Contact Process and an explanation of the conditions used in terms of the position of equilibrium, the rate of the reaction and the economics of the process.

Stage 1 - making sulfur dioxide: Sulfur is burned in the air to make sulfur dioxide Sulfur + oxygen ----> Sulfur dioxide S (I) + O2 (g) ----> SO2 (g) This IS NOT a reversible reaction Stage 2 - …

Outline the steps and conditions necessary for the industrial production ofH 2 SO 4 from its raw materials. This process is called the Contact Process (because the SO2 and O2 gases must …
