NEET Chemistry Order of Reaction MCQ Question
What is the relationship between the natural logarithm of the concentration of reactants and time for a first-order reaction?
It is a straight line with a negative slope.
It is a straight line with a positive slope.
It is a curved line that increases with time.
It is a horizontal line indicating constant concentration.
Correct Answer
Detailed Explanation
For a first-order reaction, plotting ln[R] against time gives a straight line with a slope equal to -k, indicating a negative slope as concentration decreases over time.
