Question

A chemist is planning to study a chemical equilibrium for which no measured explicit thermodynamic values are available. However, the reaction involves common chemical species. What information could a chemist use to make predictions about the equilibrium? equilibrium constants for the equilibrium reactions that can be combined to make the new equilibrium delta G^degree_f values for the reactants and products of the new reaction delta H_f and S degree values for the reactants and products of the new reaction all the above

Explanation / Answer

assume the reaction A + B ------> C + D

Kf is equilibrium constant for forward reaction and Kb equilibrium constant for backward reaction.

equilibrium cinstant Kc = Kf / Kb = conatant and

dG = -RT ln Kc

based these we have to know the equilibrium constants, Temperature , dG values and dH and dS values for calculation of dG.

so Answer : d
