Question
1) What is the average reaction rate between 0. and 1500. ss? 
Express your answer to three significant figures and include the appropriate units.
 
2)  What is the average reaction rate between 200. and 1200. ss ?
Express your answer to three significant figures and include the appropriate units.
 
3)  What is the instantaneous rate of the reaction at t=800. st=800. s?
Express your answer to two significant figures and include the appropriate units.
An average reaction rate is calculated as the change
in the concentration of reactants or products over a
period of time in the course of the reaction. An
instantaneous reaction rate is the rate at a particular
moment in the reaction and is usually determined
graphically.
The reaction of compound A forming compound B
was studied and the following data were collected:
Time (s) [A] (M)
0.
0.184
200.
0.129
500.
0.069
800.
0.031
1200.
0.019
1500.
