Consider the equilibrium reaction: A2(g)-->2A(g), A = acetic acid and A is treated as ideal gas. Gas A was evaporated (got dimerized, molar mass=120 g/mol) in a container of volume 21.45 cm3at 437K and at an external pressure of 101.9 kPa, and the container was then sealed. The mass of acid present in the sealed container was 0.0519 g. The experiment was repeated with the same container but at 471 K, and it was found that 0.0380 g of acetic acid was present. Calculate the equilibrium constant for the dimerization of the acid in the vapour and the enthalpy of vaporization.
