NEET Chemistry Order of Reaction MCQ Question
Consider a plot described in the NCERT context where ln[R] is plotted against time t for a first-order reaction. Which feature of the plot represents the rate constant k?
The slope of the line
The y-intercept of the line
The x-intercept of the line
The curvature of the line
Correct Answer
Detailed Explanation
In a plot of ln[R] against time t for a first-order reaction, the slope of the line is equal to -k, where k is the rate constant, as per the equation ln[R] = -kt + ln[R]_0.
