Question

One step in the manufacture of sulfuric acid is the oxidation of sulfur dioxide to sulfur trioxide. Consider performing this oxidation at a pressure of 1 bar with an excess of 100 mole % oxygen, using air as the oxygen source. For the optimal yield of SO₃, it is desirable to maintain the reactor at a constant temperature of 700°C. You may assume ∆hrxn° is independent of temperature. What is the effect of increasing the pressure on the extent of reaction?

Answer 1

Extent of reaction is the quantity that measures the extent in which the reaction proceeds 4 = equilibrium ninihal Vi where malus stoichiometric coefficient you increase According to bechatelier's principle rt pressur system responds by tavouri. reaction which produces tewer molecules the the 2502 (g) + 0,(9) 250 (9) 4M = -1964) Since products moles are fewer compared to reactants which include 250 2t ₂ t a source gases (N ₂ O etc). Hence the increases extent of reaction. High pressure this case increases the rate 66 the reaction.
