NEET Chemistry Order of Reaction MCQ Question
Consider a plot of ln[R] versus time for a first order reaction. Which of the following correctly describes the slope of the plot?
The slope is equal to the negative rate constant, -k.
The slope is equal to the rate constant, k.
The slope is equal to zero for a first order reaction.
The slope is equal to the initial concentration, [R]₀.
Correct Answer
Detailed Explanation
For a first order reaction, plotting ln[R] against time yields a straight line with a slope of -k, where k is the rate constant (as per equation 3.9 in the NCERT context).
