Vedclass · Answer

(B) According to Le Chatelier's principle,an increase in pressure shifts the equilibrium towards the side with a smaller number of gaseous moles.For option $A$: $\Delta n_g = (1+1) - 2 = 0$. No effect.For option $B$: $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$. $\Delta n_g = 2 - (2+1) = -1$. Since the product side has fewer moles,increasing pressure increases the yield of $SO_3$.For option $C$: $\Delta n_g = 2 - (1+1) = 0$. No effect.For option $D$: $\Delta n_g = (1+1) - (1+1) = 0$. No effect.Therefore,the correct option is $B$.

In which of the following gaseous equilibrium will an increase in pressure increase the yield of the products?
