8:00 pm	208

Express your answer to three significant figures and include the appropriate units. Use mi as an abbreviation for miles, and h for hours, or mph can be used to indicate miles per hour.

= 35.4 mph

Now consider the following reaction and data:

H2+2BrCl→2HCl+Br2

Time (s)	Br2concentration (M)
5	1.30
15	1.95

Part B

What is the average rate of formation of Br2?

Express your answer to three decimal places and include the appropriate units.

= 0.065 Ms

Part C

Based on your answer to Part B, what is the average rate of formation of HCl?

Express your answer to three decimal places and include the appropriate units.

Part D

Based on your answer to Part B or C, what is the average rate of change of H2? Remember that reactant concentrations decrease over time.

Express your answer to three decimal places and include the appropriate units.
