Q)
A dilute solution contains m mol of solute A in 1 kg of a solvent with molal elevation constant $K_b$; The solute dimerises in solution as $2A\leftrightharpoons A_2$,Show that equilibrium constant for this dimer formation is K =$\large\frac{K_b(K_bm-\Delta T_b)}{(2\Delta T_b-K_bm)^2}$,where $\Delta T_b$ is the elevation in boiling point for the given solution.(Assume molarity = molality).
