1. (a) In the experiment carried out to determine the degree of association of benzoic acid in benzene (C6H6), the cooling curves of pure benzene and benzoic acid solution prepared by dissolving 0.358 g benzoic acid in 20 mL of benzene were obtained by using Beckmann thermometer, calibrated before the experiment. The cooling curves are given in the figure below. Calculate the degree of association of benzoic acid in benzene for the given solution. K= 5.055 K kg.mol', dbenzene= 0.876 g.cm³, MBenzoic acid=122.12 g.mol-¹ T(°C) 2.88 2.38 Benzene Solution t(min)
