Which of the following conclusions concerning the concentration-time plot provided below is/are correct?
1)The concentration of substance D is decreasing over time.
2)The instantaneous reaction rate at point A is less than the instantaneous reaction rate at point B.
3)Substance D is a product of the reaction.

Question

Quizplus · Accepted Answer

1) The slope of the concentration-time plot is negative, indicating a decrease in concentration over time.
2) The instantaneous reaction rate can be determined by the slope of the tangent line at a given point. The slope at point B is steeper than that at point A, indicating a higher instantaneous reaction rate at B.
3) Since the concentration of substance D is decreasing over time, it is likely a product of the reaction.
