NEET Chemistry Order of Reaction MCQ Question
Which combination of statements about the order of reaction is correct?
The order of a reaction can be determined by the exponents in the rate law. The rate constant is dependent on temperature.
The order of reaction is always equal to the stoichiometric coefficients of the balanced equation. The rate constant changes with concentration.
For first order reactions, the rate constant remains constant regardless of the concentration. The order of reaction cannot be inferred from the balanced equation.
The rate of a reaction is solely determined by the concentration of the reactants. The order of reaction is the same for all reaction types.
Correct Answer
Detailed Explanation
The correct combination is A, as the order of a reaction is determined by the exponents in the rate law, and the rate constant is indeed affected by temperature. Other options present misconceptions regarding the definition of order and the behavior of the rate constant.
