Vedclass · Answer

(A) According to Le Chatelier's principle,a change in volume affects the equilibrium position only if there is a change in the total number of moles of gaseous species,i.e.,$\Delta n_g 
eq 0$.For option $A$: $\Delta n_g = (2) - (1 + 1) = 0$.Since $\Delta n_g = 0$,a change in volume will not shift the equilibrium,and the number of moles of components will remain unchanged.For options $B$,$C$,and $D$,$\Delta n_g 
eq 0$,so a change in volume will affect the equilibrium.

For which of the following reactions will a change in the volume of the system $NOT$ result in a change in the number of moles of the components?
