NEET Chemistry Rate of Reaction MCQ Question
Which of the following statements about the rate of reaction is correct?
The average rate of reaction can vary over time depending on the concentrations of reactants and products.
The rate of reaction is always constant regardless of the concentrations of reactants.
Instantaneous rate can be determined from the average rate by considering larger time intervals.
For zero-order reactions, the rate depends on the concentration of the reactants.
Correct Answer
Detailed Explanation
The average rate of reaction changes as the concentrations of reactants decrease over time; thus, it can vary. Instantaneous rate is defined at a specific moment and requires smaller time intervals, as stated in the context.
