Assignment 3 Kinetics At 1 atm and 25 oC, the concentration of nitrogen dioxide was measured at different times and the data are shown below.

time (s)	[NO2] (M)
0	0.0800
10	0.0480
20	0.0329
30	0.0253
40	0.0199
50	0.0150
60	0.0143
70	0.0120

Add another sheet and change the tab to read Kinetics and enter the data as shown above. Label a third column ln[NO2] and a fourth column 1/[NO2]

- include units. Use Excels formula function to calculate the values for the third and fourth columns.

1.. Plot a graph of [NO2] vs time. Write the value of R2. Is the relationship linear?

2. Plot a graph of ln[NO2] vs time. Write the value of R2. Is the relationship linear?

3.. Now plot a graph of 1/[NO2] vs time. Write the value of R2. Is this relationship linear?

Write down the algebraic relationship between the variables that are linearly related, i.e., the one relationship from questions 1, 2, & 3 above that is linear. Even though you will have the relationship in the form of y = mx + b, write the relationship with the correct entities or numbers replacing y, m, x and b . Report units as needed for any numerical values you report.

Use your answer to #4 to calculate how long it would take for the concentration to reach 0.0400M. Show your complete work.
