ntacetic acid dimerises in benzene solution, i=0.8. The % of dimerisation of acetic acid isn

Q. 1 mol $C{H}_{3}COOH$ is added in 250 g benzene. Acetic acid dimerises in benzene due to hydrogen bond. $K_b$ of benzene is 2 K $kgmo{l}^{-1}$. The boiling point has increased by 6.4 K. % dimerisation of acetic acid is :

Q. Acetic acid dimerises in vapour phase at $437K$ as $2C{H}_{3}COOH\left(g\right)\rightleftharpoons {\left(C{H}_{3}COOH\right)}_2\left(g\right)$. A mass of $0.0519g$ of acetic acid was found to have $764.3mm$ pressure at $437K$ in a container of $21.45{cm}^3$. Calculate degree of dimerisation for acetic acid dimerisation.

Q. Acetic acid forms a dimer in non polar solvent benzene through hydrogen bonding the observed molecular mass of acetic acid assuming $25\%$ dimerisation in benzene is $x$. The value of $0.875x$ is

Q. The freezing point of a solution of acetic acid (mole fraction = $0.02$) in benzene is $277.4K$. Acetic acid exists partly as a dimer $2A\rightleftharpoons A_2.$ Determine the equilibrium constant for dimerisation. Freezing point of benzene is $278.4K$ and $K_f$ for benzene is $5$.

Q. The freezing point of $0.02mol$ fraction solution of acetic acid $\left(A\right)$ in benzene $\left(B\right)$ is $277.4K$. Acetic acid exists partly as a dimer $2A=A_2$. Calculate equilibrium constant for the dimerisation. Freezing point of benzene is $278.4K$ and its heat of fusion $\Delta H_f$ is $10.042kJmo{l}^{-1}$.
