1a. Specify the reaction order for the following rate expressions: 1). rA = k(CA) 2 2) rA = k 3) rA = −kCA b. A laboratory kinetic study was performed for decomposition or decay of Chemical A, and the following data were obtained : Time, t Concentration, CAt (hr) (mg/l) 0 135 1 98 2 71 4 37 6 19 8 10 Use a spreadsheet to complete the necessary calculations and to perform a linear regression for establishing a statistically objective value for the reaction rate constant. Then use the spreadsheet's graphing tools to plot the observed data and the "best fit" regression line on the same graph to provide a graphical goodness-of-fit test.

1a. Specify the reaction order for the following rate expressions:
1). rA = k(CA) 2
2) rA = k
3) rA = −kCA
b. A laboratory kinetic study was performed for decomposition or decay of Chemical A, and the following data were obtained
: Time, t Concentration, CAt
(hr) (mg/l)
0 135
1 98
2 71
4 37
6 19
8 10
Use a spreadsheet to complete the necessary calculations and to perform a linear regression for establishing a statistically objective value for the reaction rate constant. Then use the spreadsheet's graphing tools to plot the observed data and the "best fit" regression line on the same graph to provide a graphical goodness-of-fit test.
We know,
Order of a reaction is defined as the sum of the exponents in the rate expression of a reaction.
