When a liquid is in dynamic equilibrium with its vapor at a given temperature, the tollowing conditions could exist: (I) There is no transter of molecules between the liquid and vapor. (II) The vapor pressure has a unique value. (1II) The opposing processes, (liquid to vapor) and (vapor to liquid), proceed at equal rates. (IV) The concentration of vapor is dependent on time. (a) 1I only II and III (c) I, II and III (d) II and IV 30. 0.0800 g of a compound with the empirical formula C2H2N is dissolved in 10.00 9 of bensene. The resulting solution freezes at 4.99°C.
