Question

a scientist determined the rate of an enzyme - catalyzed reaction by measuring the amount of product formed over time. the following curve was generated from the data collected. during which time interval is the reaction rate lowest? a 0 - 1 minute b 1 - 2 minutes c 2 - 3 minutes d 3 - 4 minutes e 4 - 5 minutes

Explanation:

Step1: Understand reaction - rate concept

Reaction rate is the slope of the product - time curve.

Step2: Analyze slope for each interval

The slope of the curve represents the rate of product formation. A lower slope means a lower reaction rate.
For 0 - 1 minute, the curve has a steep slope.
For 1 - 2 minutes, the slope is still relatively steep.
For 2 - 3 minutes, the slope starts to decrease.
For 3 - 4 minutes, the slope is further decreased.
For 4 - 5 minutes, the curve is almost horizontal, indicating the lowest slope.

Answer:

E. 4 - 5 minutes
