NEET Chemistry Rate of Reaction MCQ Question
Which of the following statements about reaction rates and order is correct?
The order of a reaction is determined by the slowest step of the reaction mechanism.
The rate law must always include the stoichiometric coefficients of the reactants.
The rate constant is dependent on the concentrations of the reactants in a reaction.
For a zero-order reaction, the half-life is independent of the initial concentration of reactants.
Correct Answer
Detailed Explanation
The order of a reaction is indeed determined by the slowest step of the reaction mechanism, aligning with the NCERT content stating that the order is given by the slowest step. In contrast, the rate law does not always equal stoichiometric coefficients, the rate constant is independent of concentration, and the half-life for zero-order reactions is directly proportional to initial concentration.
