Use the data in Figure 13.1 to calculate the instantaneous rate of disappearance of the reactant at 10 seconds.
Strategy

The instantaneous rate is the slope of the tangent, so place a ruler on the graph, draw the tangent, and calculate the slope. Although two people might not place the ruler in exactly the same position, slopes estimated from graphs are surprisingly accurate.
