Question

Which of the following statements does not apply to a given rate law corresponding to a specific reaction?

• A. As the temperature changes, the rate of reaction changes.
• B. As the reaction rate changes, the rate constant does not change.
• C. As the concentration of the reactants changes, the unit of the rate constant changes.
• D. As the concentration of the reactants changes, the rate of reaction changes.

Answer 1

The correct option is C As the concentration of the reactants changes, the unit of the rate constant changes.

The unit of the rate constant and its value is fixed for a particular order of a reaction. It does not depend on the change of concentration of reactants but rate constant value depends on temperature.

So, (C) option does not apply to a given rate law corresponding to a specific reaction.
