Acetic acid forms a dimer in the gas phase The dimer is held together by two hydrogen bonds with a total strength of 66.5 kJ per mole of dimer. At 25oC, the equilibrium constant for the dimerisation is 1.3×103 (pressure in atm). What is magnitude △S0 for the reaction? Assume that △H does not vary with temperature.

Answer» Acetic acid forms a dimer in the gas phase The dimer is held together by two hydrogen bonds with a total strength of 66.5 kJ per mole of dimer. At $25^{o} C,$ the equilibrium constant for the dimerisation is $1.3 \times 10^{3}$ (pressure in atm). What is magnitude $△ S^{0}$ for the reaction? Assume that $△ H$ does not vary with temperature.
