NEET Chemistry Order of Reaction MCQ Question
What is the characteristic of a first order reaction regarding the relationship between the natural logarithm of concentration and time?
It gives a straight line when plotted.
It results in a parabolic curve on a graph.
It is independent of time.
It shows an exponential decrease in concentration.
Correct Answer
Detailed Explanation
A first order reaction, when the natural logarithm of concentration is plotted against time, yields a straight line with a slope of -k, indicating a linear relationship between ln[R] and time.
