In the gas phase, acetic acid exists as an equilibrium of monomer and dimer molecules. (The dimer consists of two molecules linked through hydrogen bonds.) The equilibrium constant, , at 25 °C for the monomer-dimer equilibrium has been determined to be . Assume that acetic acid is present initially at a concentration of mol/L at 25 °C and that no dimer is present initially. a What percentage of the acetic acid is converted to dimer? Percentage = %

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
