Equilibrium Question 873

Question: Consider the reaction equilibrium, $ 2S{O_{2(g)}} $ + $ {O_{2(g)}} $

$ \rightarrow $ $2S{O_{3(g)}} $ ; $ \Delta H{}^\circ $ = –198kJ. On the basis of Le-Chatelier’s principle, the condition favourable for the forward reaction is

Options:

A) Lowering of temperature as well as pressure

B) Increasing temperature as well as pressure

C) Lowering the temperature and increasing the pressure

D) Any value of temperature and pressure

Show Answer

Answer:

Correct Answer: C

Solution:

It is an exothermic reaction hence low temperature and increasing pressure will favour forward reaction.
