Question

The thermodynamic properties for a reaction are related by the equation that defines the standard free energy, ?G?, in kJ/mol:

The thermodynamic properties for a reaction are related by the equation that defines the standard free energy. AG theta. in kJ/mol delta G theta =delta H theta-T delta S theta where AH0 is the standard enthalpy change in kJ/moland AS degree is the standard entropy change in J/ (nol middot K) A good approximation of the free energy change at other temperatures. AG?, can also be obtained by utilizing this equation and assuming enthalpy (delta H theta) and entropy (delta s theta) change little with temperature. Part A For the decomposition of banum carbonate, consider the following thermodynamic data: Calculate the temperature in Kelvins above which this reaction is spontaneous. Express your answer to four significant figures and include the appropriate units.

Explanation / Answer

Assume delta G to be just negative for reaction to be spontaneous..

=> 0= deltaH - T* deltaS

=> T = deltaH / deltaS

T = 1416 K
