A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_(b) . The solute dimerises in the solution according to the following equation. The degree of association is (a) : 2A hArrA_(2) The degree of assoicition is equal to : a) a = ((K_(b)x - /_\T_(b)))/(/_\T_(b)2) b) a = (2(K_(b)x - /_\T_(b)))/(K_(b)x) c) a =2 + (2/_\T_(b))/(K_(b)x) d) a = (/_\T_(b))/(2K_(b)x)
