NEET Chemistry Order of Reaction MCQ Question
In a graph where ln[R] is plotted against time t for a first order reaction, which feature of the graph corresponds to the initial concentration of the reactant [R]₀?
Intercept on the ln[R] axis
Slope of the line
Intercept on the time axis
Area under the curve
Correct Answer
Detailed Explanation
In a plot of ln[R] against time t for a first order reaction, the intercept on the ln[R] axis corresponds to ln[R]₀, which represents the initial concentration of the reactant.
