Which statements correctly describe a dynamic chemical equilibrium?
Hints
- Dynamic means the reactions keep running, not that they stop.
- Constant concentrations and halted reactions are not the same claim.
Show the answer
- A. The system can shift if an external stress is applied
- C. Concentrations of reactants and products remain constant over time
- D. Forward and reverse reaction rates are equal
Why
At dynamic equilibrium the reaction continues at equal forward and reverse rates, it has not stopped. Macroscopic concentrations are constant but the reaction is still occurring microscopically.
