The second experiment proceeds at the higher rate. I2 in the gaseous state would experience more collisions
with gaseous H2.

a) Calculate the slope of the line connecting (0, [C]o) and (tf, [C]f) (final time and concentration). The
negative of this slope is the average rate.
b) Calculate the negative of the slope of the line tangent to the curve at t = x.
c) Calculate the negative of the slope of the line tangent to the curve at t = 0.
d) If you plotted [D] versus time, you would not need to take the negative of the slopes in (a)–(c) since [D]
would increase over time.
