Question

If a $\Delta G^{\circ}$ for a given reaction is known one may determine all the following except the

• A. direction of spontaneous change at the standard conditions
• B. position of equilibrium at temperature for which $\Delta G^{\circ}$ is known
• C. usefulness of catalyst in controlling the reaction
• D. maximum amount of useful work that can be produced at standard conditions

Answer 1

Answer: (C)

Usefulness of catalyst in controlling the reaction can be determined by enthalpy not by free energy.
