MCQ
Consider the reaction equilibrium, $2S{O_{2(g)}}$+${O_{2(g)}}$ $\rightleftharpoons$ $2S{O_{3(g)}}$;  $\Delta H^\circ =\, -198\,kJ$. On the basis of Le-Chatelier’s principle, the condition favourable for the forward reaction is
  • A
    Lowering of temperature as well as pressure
  • B
    Increasing temperature as well as pressure
  • Lowering the temperature and increasing the pressure
  • D
    Any value of temperature and pressure

Answer

Correct option: C.
Lowering the temperature and increasing the pressure
(c) It is an exothermic reaction hence low temperature and increasing pressure will favour forward reaction
