Vedclass · Answer

(B) According to Le Chatelier's principle,for a reaction at equilibrium,an increase in pressure shifts the equilibrium towards the side with a smaller number of moles of gaseous species.For reaction $A$: $\Delta n_g = (1+1) - 1 = 1$. Increasing pressure shifts equilibrium to the left.For reaction $B$: $\Delta n_g = 2 - (1+1) = 0$. The number of moles of gaseous reactants and products is equal,so pressure change has no effect on the yield.For reaction $C$: $\Delta n_g = 2 - (1+3) = -2$. Increasing pressure shifts equilibrium to the right (yield increases).For reaction $D$: $\Delta n_g = 2 - (2+1) = -1$. Increasing pressure shifts equilibrium to the right (yield increases).Therefore,in reaction $B$,the yield does not increase with high pressure.

In which of the following reactions does the yield of the product not increase by the application of high pressure?
