Question

the rate of oxygen production equaled the rate of oxygen consumption during which of the following time periods?
g to h
g to k
j to k
i to j
h to i

Explanation:

Step1: Analyze the graph

The rate of oxygen production equals the rate of oxygen consumption when there is no net change in oxygen concentration. This occurs when the slope of the graph (which represents the rate of change of oxygen concentration) is zero.

Step2: Check each segment

• G to H: The slope is positive (oxygen concentration is increasing, so production > consumption).
• G to K: Not a single - segment.
• J to K: The slope is negative (oxygen concentration is decreasing, so consumption > production).
• I to J: The slope is positive (oxygen concentration is increasing, so production > consumption).
• H to I: The slope is zero (no net change in oxygen concentration, so production = consumption).

Answer:

H to I
