NEET Chemistry (general) Assertion Reason Question
Assertion (A): The rate of a reaction is proportional to the concentration of the reactants raised to specific powers. | Reason (R): The stoichiometric coefficients of reactants in a balanced equation always determine the exponents in the rate expression.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The assertion is true because the rate of a reaction is related to the concentration of reactants raised to certain powers, as described by the rate law. However, the reason is false because the exponents in the rate expression (rate law) do not necessarily correspond to the stoichiometric coefficients; they are determined experimentally.
