Current Question (ID: 21133)

Question:

$\text{Consider the reaction equilibrium:}$ $2\text{SO}_2(g) + \text{O}_2(g) \rightleftharpoons 2\text{SO}_3(g); \quad \Delta H^\circ = -198 \text{ kJ}$ $\text{On the basis of Le-Chatelier's principle, the condition favorable for the forward reaction is:}$

Options:

1. $\text{lowering of temperature as well as pressure}$
2. $\text{increasing temperature as well as pressure}$
3. $\text{lowering the temperature and increasing the pressure}$
4. $\text{Any value of temperature and pressure}$

Solution:

$\text{Hint: Forward reaction is exothermic in nature}$ $\text{The reaction is an example of an exothermic reaction. Lower the temperature favors a forward reaction.}$ $\text{The backward reaction is an endothermic reaction hence, increasing the temperature favors the backward reaction.}$ $\text{For the given reaction, the } \Delta n_g \text{ value is negative. Hence if pressure increases the reaction will go at the forward direction.}$ $\text{Thus, option third is the correct answer.}$
