NEET Chemistry Rate of Reaction MCQ Question
Which of the following statements about the rate of a chemical reaction is correct?
The average rate of a reaction can be expressed in terms of the change in concentration over time.
The rate of a reaction is always equal to the stoichiometric coefficients of the reactants.
Rate laws are independent of the concentrations of reactants involved in the reaction.
The units of rate of reaction do not depend on the concentration of reactants.
Correct Answer
Detailed Explanation
The average rate of a reaction is defined as the change in concentration of reactants or products over time, as indicated in the NCERT context. Other options misrepresent the relationship between rate, stoichiometry, and concentration.
