Jan 30, 2023 · This Modules explain the reasons for the conditions used in the process by considering the effect of proportions, temperature, pressure and catalyst on the composition of the equilibrium mixture, the rate of the reaction and the economics of the process.
Similar to the Haber process, the pressure and temperature used need to be considered; The equation for the main stage of the Contact process is: 2SO 2 + O 2 2SO 3. Temperature: 450 ºC. High temperature favours the reverse reaction as it is endothermic So, a higher yield of reactants will be made
This page describes the Contact Process for the manufacture of sulphuric acid, and then goes on to explain the reasons for the conditions used in the process. It looks at the effect of proportions, temperature, pressure and catalyst on the composition of the equilibrium mixture, the rate of the reaction and the economics of the process.
What is the temperature and pressure used in the contact process? The temperature is 450°C and the pressure is 2 atmospheres. Test Your Knowledge On Contact Process!
You need to recall the temperature, pressure and catalyst needed for the Contact process and the equation for the main stage only.
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Platinum was originally used as the catalyst for this reaction; however, as it is susceptible to reacting with arsenic impurities in the sulfur feedstock, vanadium (V) oxide (V 2 O 5) is now preferred. [1] History.
Stage one – making sulfur dioxide. In the first stage of the contact process, sulfur is burned in air to make sulfur dioxide: sulfur + oxygen → sulfur dioxide. S (l) + O 2 (g) → SO 2 (g ...
