Problem

The overall reaction is C4H9Cl (aqueous) plus H2O (liquid) goes to C4H9OH (aqueous) + HCl (aqueous). The x-axis is time (seconds), ranging from 0 to 900 with intervals of 100. The y-axis is concentration of C4H9Cl (molar) ranging from 0 to 0.100 with inter-vals of 0.010. The instantaneous rate at time t equals the slope of tangent to the line at time t; where the slope is the hypotenuse of a triangle touching the line with a height equal to the change in concentration of CH4H9Cl and length equal to change in time. For example, the instantaneous rate at time equals 0 seconds (initial rate) is 0.100 molar, and the instantaneous rate at time 600 sec-onds equals 0.030 molar. Data points of time in units of seconds versus concentration in molar units are: 0, 0.100, point 2, 100, 0.083, point 3, 200, 0.068, point 4, 300, 0.055, point 5, 400, 0.045, point 6, 500, 0.038, point 7, 600, 0.030, point 8, 700, 0.025, point 9, 800, 0.020, and point 10, 900, 0.017.
