Question

The concentration-time dependence for a first-order reaction is: 
 At which point on the curve is the reaction fastest?

Quizplus · Accepted Answer

The reaction is fastest at the beginning (point A) when the concentration is highest and gradually decreases throughout the reaction. This is because the rate of a first-order reaction is directly proportional to the concentration of the reactant. As the concentration decreases, the rate of the reaction also decreases. Therefore, the slope of the curve is steepest at the beginning and gradually levels off, indicating a slower rate of reaction at later times.
