Date: Name: Class: Use the following table to answer the questions regarding the equation below: A + B 2C + D Time (s) [A] (mol/L) [C] (mol/L) 0.00 3.20 0.00 3.00 2.42 1.58 6.00 1.95 2.50 9.00 1.63 3.14 12.00 1.40 3.62 15.00 1.23 3.94 18.00 1.10 4.18 1. (a) On a set of concentration-time axes, plot a graph of [A] versus time. Use the grid below, a separate sheet of graph paper, or a spreadsheet program. (b) Explain the shape of the graph. (c) Draw a secant to the curve in the interval from t = 0.0 s to t = 3.0 s. Determine the slope of the secant.

Date: Name: Class: (d) What is the average rate of decrease of [A] from t = 0.0 s to t = 3.0 s? (e) What is the average rate of decrease of [A] between 3.0 s and 6.0 s? (f) How do you account for the difference in answers to questions (d) and (e)? (g) Draw a tangent to the curve at 6.0 s. Determine the slope of the tangent. (h) Interpret your answer for (g) in terms of rate. 2. (a)
