Vedclass · Answer

(C) For the dissociation of ammonium chloride: $NH_4Cl(s) \rightleftharpoons NH_3(g) + HCl(g)$.Here,the number of moles of gaseous products $n = 2$.The relationship between degree of dissociation $(x)$,theoretical vapour density $(D_t)$,and observed vapour density $(D_o)$ is given by: $x = \frac{D_t - D_o}{D_o(n - 1)}$.For complete dissociation,$x = 1$ and $n = 2$.Substituting these values: $1 = \frac{D_t - D_o}{D_o(2 - 1)}$.$1 = \frac{D_t - D_o}{D_o} \implies D_o = D_t - D_o \implies 2D_o = D_t$.Therefore,$D_o = \frac{D_t}{2}$.

Which of the following equations is correct for the vapour density of completely dissociated ammonium chloride?
