NEET Chemistry Order of Reaction Assertion Reason Question
Assertion (A): The order of a reaction can be determined by plotting the natural logarithm of reactant concentration against time. | Reason (R): A straight line with a negative slope indicates a first-order reaction.
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.
Correct Answer
Detailed Explanation
In the NCERT context, plotting ln[R] against time gives a straight line with a negative slope for first-order reactions, confirming both statements.
