The free energy change for a chemical reaction is given by (where, K = equilibrium constant)________________?
Correct answer: B. -RT ln K
- A. RT ln K
- B. -RT ln K
- C. -R ln K
- D. T ln K
Explanation
At equilibrium, the standard Gibbs free-energy change is related to the equilibrium constant by ΔG° = −RT ln K. A large K therefore corresponds to a negative standard free-energy change.
