Chemical Process In multistage equilibrium conversion of SO₂ to SO₃ (2SO₂ + O₂ ⇋ 2SO₃), the reverse reaction becomes appreciable at a temperature of 550° C. The percentage equilibrium conversion of SO₂ to SO₃ can be increased by Putting more quantity of V₂O₅ catalyst in the converter Increasing the oxygen concentration Maintaining low temperature & pressure in the converter Removing some quantity of SO₃ during intermediate stage Putting more quantity of V₂O₅ catalyst in the converter Increasing the oxygen concentration Maintaining low temperature & pressure in the converter Removing some quantity of SO₃ during intermediate stage ANSWER DOWNLOAD EXAMIANS APP
