Consider the reaction equilibrium 2SO2( g)+O2( g)⇌2SO3( g);ΔH0=−198 kJ2 \mathrm{SO}_2(\mathrm{~g})+\mathrm{O}_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{SO}_3(\mathrm{~g}) ; \Delta \mathrm{H}^0=-198 \mathrm{~kJ}. On the basis of Le Chatelier's principle, the condition favourable for the forward reaction is

Options

  1. Aincreasing temperature as well as pressure
  2. Blowering the temperature and increasing the pressure
  3. Cany value of temperature and pressure
  4. Dlowering of temperature as well as pressure

Correct answer

B. lowering the temperature and increasing the pressure

Step-by-step solution

Due to exothermicity of reaction low or optimum temperature will be required. Since 3 moles are changing to 2 moles. ∴\therefore High pressure will be required.
