Hydrogen Iodide, HI, decomposes by the following reaction:

2HI(g) --> H2(g) + I2(g)

given the following data

Time, (s) [HI], mM

0 10

1000 4.4

2000 2.8

3000 2.1

4000 1.6

5000 1.3

Answer the following questions:

a) What is the average rate of reaction from 2000 s to 5000 s? Choose from answers A-D.

b) What method could be used to find the instantaneous rate at 2500 s? Choose from answers E-H.

6 options:

A) -0.0026 mM s-1

B) -0.0017 mM s-1

C) -0.00093 mM s-1

D) -0.00050 mM s-1

E) Find the slope of the line tangent to the curve at 2500 s.

F) Calculate the average rate from 0 to 5000 s and divide by 2.

G) Graph the data only from 1000 to 4000 seconds and find the slope of the linear curve across that data.

H) Calculate the average rate from 2000 to 3000 s.
