NEET Chemistry Order of Reaction MCQ Question
What is the relationship between the slope of the plot of ln[R] versus time for a first order reaction and the rate constant?
The slope equals -k
The slope equals k
The slope equals 2k
The slope equals -2k
Correct Answer
Detailed Explanation
For a first order reaction, when plotting ln[R] against time, the slope is equal to -k, indicating the negative rate constant. This is supported by the equation presented in the NCERT context.
