Reactions in which a substance decomposes by losing CO2 are called decarboxylation reactions. The decarboxylation of acetic acid proceeds as follows.

CH3COOH(l)-->CH4(g)+CO2(g)

Calculate the minimum temperature at which this process will be spontaneous under standard conditions. Assume that ΔH° and ΔS° do not vary with temperature. (CH3COOH(l): ΔH°f=-487.0 kj/mol, ΔS°=159.8J/mol K).

    For reactions carried out under standard-state conditions, the equation ΔG = ΔH − TΔS becomes ΔG° = H° − TΔS°. Assuming ΔH° and ΔS° are independent of temperature, one can derive the equation: ln( K2 K1 ) = ΔH° R ( T2 − T1 T1T2 ) where K1 and K2 are the equilibrium constants at T1 and T2, respectively. Given that at 25.0°C, Kc is 4.63×10−3 for the reaction N2O4(g) longrightleftarrow 2NO2(g) ΔH° = 58.0 kJ/mol calculate the equilibrium constant...
