NEET Chemistry Rate of Reaction MCQ Question
Consider a plot where concentration of reactant [R] is plotted against time for a zero order reaction. The graph is a straight line with a negative slope. Which of the following correctly describes the slope of this line?
The slope is equal to the negative rate constant.
The slope is equal to the positive rate constant.
The slope represents the order of the reaction.
The slope is proportional to the initial concentration of [R].
Correct Answer
Detailed Explanation
For a zero order reaction, the concentration vs. time plot is a straight line with a slope equal to -k, where k is the rate constant. This is derived from the equation [R] = [R]₀ - kt.
