Question #8c999

Answer 1

Here are the steps.

Explanation:

(a) The order of the reaction

For the reaction `"A → Products"`, the rate law is

`"Rate" = k["A"]^n`

Use experiments 1 and 2 and the method of initial rates to determine the value
of `n`.

(b) The rate constant

Insert your value of `n` and the data from experiment 1 or 2 and calculate the value of `k` at 25 °C.

Repeat for experiment 3 and calculate the value of `k` at 35 °C.

(c) The activation energy

Use the rate constants at 25 °C and 35 °C to calculate `(Δlnk)/(Δ(1/T))`.

`(Δlnk)/(Δ(1/T)) = "-"E_text(a)/R`

Then calculate `E_text(a)`.
