NEET Chemistry Chemical Equilibrium Assertion Reason Question
Assertion (A): At chemical equilibrium, the concentration of reactants and products remains constant over time. | Reason (R): At equilibrium, the forward and reverse reaction rates are equal.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
At chemical equilibrium, the concentrations of reactants and products remain constant because the forward and reverse reaction rates are equal, as described in NCERT Chunk 2.
