Question
In a chemical equilibrium, the concentrations of reactants and products:
Correct Answer
Option C is the correct answer.
Detailed Explanation
At equilibrium, the forward and reverse reaction rates are equal, so the net change in the concentrations of reactants and products is zero. This means their concentrations become constant, though not necessarily equal to each other.
Hint
Equilibrium is a state of balance where macroscopic properties do not change.
