Notice on the graph that the time period between 0 and 3 minutes forms a straight line on the graph. What does this indicate about the rate of the reaction?

The graph is positive.

Explanation:

Straight line on the graph indicates that the rate of reaction is positive which means that reaction intensity increases with the passage of time. OR in other words, the reaction produces more products with the passage of time and no decrease occurs in their rate because the graph is not coming downward or changing so that's why the graph go in the straight line.
