NEET Chemistry Chemical Equilibrium MCQ Question
Which of the following statements about chemical equilibrium is correct?
At equilibrium, the concentrations of reactants and products remain constant.
The concentration of a pure solid or liquid changes with the amount present.
Only products are formed at equilibrium in a reversible reaction.
Reactions that reach equilibrium do not proceed in either direction.
Correct Answer
Detailed Explanation
At equilibrium, the concentrations of various species in the reaction mixture do not change, which is highlighted in the context of reactions classified based on their extent of completion. The other options reflect misconceptions about the nature of equilibrium.
