The order of reaction can never be zero.

Assertion (A) : The order of a reaction can be zero or a fraction . Reason (R) : Order cannot be determined from the balanced equation.

Order of a reaction can be zero.

Molecularity of a reaction can never be zero.(True/False)

Assertion: Order of reaction can never be fractional for an elementary reaction. Reason: An elementary reaction takes place by one step mechanism.

Assertion (A) : The order of a reaction can be fractional but molecularity is never fractional. Reason (R ): The order of reaction does not depend upon the stoichiometric coefficients of a balanced equation.
