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?

Question

Quizplus · Accepted Answer

All of the options given provide information that could be useful in predicting the equilibrium. Option A gives the equilibrium constants for the reactants that can be used to determine the overall equilibrium constant. Option B provides standard free energy of formation values for the reactants and products, which can be used in calculating the overall reaction Gibbs free energy. Option C provides the standard free energy of formation values for the reactants and products at different temperatures, which can be used in predicting the effect of temperature on the equilibrium. Therefore, using all of the provided information could be most helpful in predicting the equilibrium.
