What is true about a reaction at equilibrium?
The forward rate equals the reverse rate accurately defines or describes the concept asked in this question. Within Kinetics and Thermodynamic, precise definitions and terminology are essential for clear scientific communication. The other options (The forward rate is greater than the reverse rate, The reaction stops completely, and ΔG is highly positive) either describe related but distinct concepts, use incorrect terminology, or confuse similar-sounding terms that have different scientific meanings. A thorough understanding of exact definitions helps distinguish between closely related biological concepts and is crucial for competitive examinations.
